Who serves in the active-duty ranks of the U.S. all-volunteer
military? Conventional wisdom holds that military service
disproportionately attracts minorities and men and women from
disadvantaged backgrounds. Many believe that troops enlist because
they have few options, not because they want to serve their country.
Others believe that the war in Iraq has forced the military to lower
its recruiting standards.
Previous Heritage Foundation studies that examined the backgrounds
of enlisted personnel refute this interpretation.[1] This report
expands on those studies by using an improved methodology to study
the demographic characteristics of newly commissioned officers and
personnel who enlisted in 2006 and 2007.
Any discussion of troop quality must take place in context. A
soldier's demographic characteristics are of little importance in the
military, which values honor, leadership, self-sacrifice, courage,
and integrityqualities that cannot be quantified. Nonetheless, any
assessment of the quality of recruits can take place only on the
basis of objective criteria. Demographic characteristics are a poor
proxy for the quality of those who serve in the armed forces, but
they can help to explain which Americans volunteer for military
service and why.
Based on an understanding of the limitations of any objective
definition of quality, this report compares military volunteers to
the civilian population on four demographic characteristics:
household income, education level, racial and ethnic background, and
regional origin. This report finds that:
U.S. military service disproportionately attracts enlisted personnel
and officerswho do not come from disadvantaged backgrounds. Previous
Heritage Foundation research demonstrated that the quality of
enlisted troops has increased since the start of the Iraq war. This
report demonstrates that the same is true of the officer corps.
Members of the all-volunteer military are significantly more likely
to come from high-income neighborhoods than from low-income
neighborhoods. Only 11 percent of enlisted recruits in 2007 came from
the poorest one-fifth (quintile) of neighborhoods, while 25 percent
came from the wealthiest quintile. These trends are even more
pronounced in the Army Reserve Officer Training Corps (ROTC)
program, in which 40 percent of enrollees come from the wealthiest
neighborhoodsa number that has increased substantially over the past
four years.
American soldiers are more educated than their peers. A little more
than 1 percent of enlisted personnel lack a high school degree,
compared to 21 percent of men 18–24 years old, and 95 percent of
officer accessions have at least a bachelor's degree.
Contrary to conventional wisdom, minorities are not overrepresented
in military service. Enlisted troops are somewhat more likely to be
white or black than their non-military peers. Whites are
proportionately represented in the officer corps, and blacks are
overrepresented, but their rate of overrepresentation has declined
each year from 2004 to 2007. New recruits are also disproportionately
likely to come from the South, which is in line with the history of
Southern military tradition.
The facts do not support the belief that many American soldiers
volunteer because society offers them few other opportunities. The
average enlisted person or officer could have had lucrative career
opportunities in the private sector. Those who argue that American
soldiers risk their lives because they have no other opportunities
belittle the personal sacrifices of those who serve out of love for
their country.
This report proceeds in two parts.
First, it examines the demographic characteristics of the enlisted
personnel in 2006 and 2007, using new data from the Defense Manpower
Data Center.
Second, it examines the same demographic characteristics for 2007
graduates from the United States Military Academy (USMA) at West
Point[2] and for members of the Army ROTC who were commissioned
between 2004 and 2007 or enrolled in the Army ROTC as of March 2007.
Officers who were commissioned in 2004 would have enrolled before the
start of the war on terrorism, while those enrolled in 2007 were well
aware that they were signing up during wartime. This makes it
possible to assess whether the war in Iraq has degraded the officer
corps' standards.

Enlisted Personnel
The Defense Manpower Data Center provided The Heritage Foundation
with data on enlisted recruits for all branches of the military in
2006 and 2007.[3] These data included the recruits' racial and
ethnic background, their educational attainment when they enlisted,
and information connecting recruits to their home census tracts.
Using census tracts enables a more precise analysis of the recruits'
family income than previous Heritage Foundation reports, which had
data available only at the three-digit and five-digit Zip code
tabulation area level.
Household Income. Enlisted recruits in 2006 and 2007 came primarily
from middle-class and upper-middle-class backgrounds. Low-income
neighborhoods were underrepresented among enlisted troops, while
middle-class and high-income neighborhoods were overrepresented.
Individual or family income data on enlistees do not exist. The
Defense Department does not maintain records on the household income
of recruits or officers. Examining the earnings of most recruits
before they joined the military is not possible because, for most of
them, their first full-time job is in the military.
Instead, we approximated the recruits' household incomes by
assigning each recruit the median household income of the census
tract in which they lived. This approximates their parents' economic
status. For example, 10 recruits in 2006 came from census tract
013306 in San Diego. Accordingly, we assigned to each of these 10
recruits a median household income of $57,380 per year (in 2008
dollars), the median income of that tract in the 2000 Census.
Census tracts are far smaller and more homogenous than five-digit Zip
code tabulation areas. While the average five-digit Zip code
tabulation area contains almost 10,000 residents, census tracts
average approximately 4,000 residents.[4] Using census tract data
consequently allows for a more precise imputation of household income
than was possible in previous reports and, correspondingly, a more
accurate analysis of how the recruits differ from the civilian population.
Using the median household incomes in their census tracts, the
average household income for all 2006 recruits was $54,834 per year
(in 2008 dollars).[5] The average enlisted recruit in 2007 had a
household income of $54,768. This is modestly above the national
average of $50,428. Chart 1 shows the distribution among enlisted
recruits and the population as a whole by household income quintile.
As Chart 1 shows, low-income families are underrepresented in the
military, and high-income families are overrepresented. Individuals
from the bottom household income quintile make up 20.0 percent of the
population of those who are 18–24 years old but only 10.6 percent of
the 2006 recruits and 10.7 percent of the 2007 recruits. Individuals
in the top two quintiles make up 40.0 percent of the population, but
49.3 percent of the recruits in both years.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart1.gif
Chart 2 shows the household income distribution of enlisted recruits
for 2006 and 2007 in more detail. It also shows the difference in
income distribution between enlisted forces and the overall civilian
population.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart2.gif
Every income category above $40,000 per year is overrepresented in
the active-duty enlisted force, while every income category below
$40,000 a year is underrepresented. Low-income families are
significantly underrepresented in the military. U.S. military
enlistees disproportionately come from upper-middle-class families.
Members of America's volunteer army are not enlisting because they
have no other economic opportunities. Most recruits come from
relatively affluent families and would likely earn above-average
wages if they did not join the military.
Education. Contrary to popular perceptions, America's enlisted troops
are not poorly educated. Previous Heritage Foundation studies found
that enlisted troops were significantly more likely to have a high
school education than their peers. This is still the case. Only 1.4
percent of enlisted recruits in 2007 had not graduated from high
school or completed a high school equivalency degree, compared to
20.8 percent of men ages 18 to 24. America's soldiers are less
likely than civilians to be high school dropouts.
The military requires at least 90 percent of enlisted recruits to
have high school diplomas.[6] Most enlisted recruits do not have a
college degree because they enlist before they would attend college.
However, many recruits use the educational benefits offered by the
military to attend college after they leave the armed forces.
More evidence of the quality of America's enlisted forces comes from
the standardized Armed Forces Qualifying Test (AFQT) that the
military administers to all recruits. Over two-thirds of enlisted
recruits scored above the 50th percentile on the AFQT. The military
tightly restricts how many recruits it accepts with scores below the
30th percentile, and only 2.3 percent of recruits in 2007 scored
between the 21st and 30th percentiles (Category IVA; see Chart 3).
The military does not accept any recruits in the bottom 20 percent.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart3.gif
Race.The all-volunteer force was instituted in 1973 amid concerns
over whether the military could maintain race representation
proportional to the overall population. In a time of war, people and
policymakers would be even more concerned if the burden of war fell
disproportionately on certain sections of the population.[7]
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_table1sm.gif
As reported in Table 2, the percentage of white active-duty recruits
with no prior military service was 65.3 percent in 2006 and 65.5
percent in 2007. Based on calculations from the Integrated Public Use
Microdata Series (IPUMS), almost 62 percent of the U.S. male
population ages 18 to 24 classified themselves as white in
2006.[8] The troop-to-population ratio in these years was 1.05,
indicating that the representation of whites in the military is
similar to, although slightly above, their representation in the
overall population.[9]
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_table2.gif
The representation of blacks in the military is also above their
population representation, with recruit-to-population ratios of 1.03
in 2006 and 1.08 in 2007. The percentage of Asian and Pacific
Islander recruits is smaller than their population representation,
with recruit-to-population ratios of 0.94 in 2006 and 0.93 in 2007.
American Indian and Alaskan natives are largely overrepresented in
the military compared to their representation in the overall
population. In 2006, the IPUMS reported that less than 1 percent of
males ages 18 to 24 characterized themselves as American Indian or
Alaskan. Yet this group accounted for 2.16 percent of new enlisted
recruits in 2006 and 1.96 percent in 2007. This group is the most
overrepresented among new recruits, with troop-to-population ratios
of 2.96 in 2006 and 2.68 in 2007.
The population percentages and ratios for Hispanics are presented in
Table 3. Hispanics are largely underrepresented among new recruits,
with troop-to-population ratios of 0.64 in 2006 and 0.65 in 2007.
Compared to the previous versions of this paper,[10] the Hispanic
indicator variable had more complete responses, with many fewer
recruits declining to indicate Hispanic ethnicity. However, the
nonresponse rates for the Hispanic ethnicity indicator variable
were still large enough that they may confound the results of the
Hispanic analysis. If only recruits who responded to the Hispanic
ethnicity question are considered, we still find that this group is
underrepresented in the military.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_table3.gif
Region.Representation by census region and division for recent
active-duty military enlistees is found in Map 1. Similar to previous
Heritage Foundation reports on the regional representation of troops,
we find that the strong Southern military tradition continues with
the 2006 and 2007 enlisted recruits. The South accounts for more than
40 percent of new enlisteesa proportional overrepresentation.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_map1.gif
The Northeast is underrepresented in the enlisted population, while
the Midwest and West are roughly proportionally represented. Map 2
shows the enlisted representation ratios for each state for 2007
enlistees with no prior military service. The figures for 2006 are
in Table A1 in the Appendix.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_map2.gif
The Officer Corps
The conventional wisdom, which mistakenly holds that Americans
soldiers enlist because they are disadvantaged and have limited
opportunities, does not extend to the officer corps. The
stereotypical military officer is highly educated and comes from an
affluent family. This stereotype is largely correct.
The Defense Manpower Data Center provided The Heritage Foundation
with data on officers who were commissioned in the Army Reserve
Officer Training Corps between 2004 and 2007 and cadets who were
enrolled in the Army ROTC as of March 27, 2007. The military also
provided information on the 2007 graduates of the U.S. Military
Academy at West Point. Although these data do not represent all
officers, they provide significant insight into the demographic
characteristics of the officer corps: 39 percent of active-duty
officers were commissioned through the ROTC,[11] and 25 percent of
new army lieutenants graduated from West Point.[12]
Household Income.America's officers come from relatively well-off
neighborhoods. The same methodology used to assess the income of the
enlisted personnel shows that the average candidate enrolled in the
Army ROTC in March 2007 came from a neighborhood with a median
household income of $64,083 (in 2008 dollars)well above the national
figure of $50,428. The discrepancy is even greater for West Point
graduates, for whom the average graduate came from a neighborhood
with a median income of $75,367.
Only 7.8 percent of ROTC candidates in 2007 came from neighborhoods
in the bottom household income quintile, while 40.0 percent come from
neighborhoods in the top income quintile. Chart 5 shows the
difference between the income distributions of civilians and
officers who were commissioned in the ROTC or graduated from West
Point. Unsurprisingly, both groups of officers come from
higher-income neighborhoods.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart4.gif
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart5.gif
The greatest discrepancy between officer and civilian backgrounds
occurs in neighborhoods with median earnings above $100,000. While
3.4 percent of neighborhoods nationwide have median earnings above
$100,000, 9.5 percent of ROTC commissions and 21.1 percent of USMA
graduates come from these high-income neighborhoods. Most of the men
and women who risk their lives serving as U.S. military officers
probably could have earned high salaries if they had chosen civilian careers.
The vast majority of officers commissioned in 2004 entered the ROTC
four years earlier in 2000, before the September 11 terrorist
attacks. Those who were commissioned or who were enrolled in the ROTC
in 2007 became officer candidates in wartime conditions knowing that
they could be deployed to Iraq or Afghanistan. If the strain of the
global war on terrorism has forced the military to lower its
standards in the officer corps, then the quality of officers
commissioned in the ROTC would have fallen since 2004.
The opposite has occurred. Chart 4 shows the income distribution of
ROTC officers commissioned in 2004, 2005, and 2006 and those who
enrolled or were commissioned in 2007. The median neighborhood income
of candidates entering the ROTC has increased by an average of 4.9
percent since 9/11 and the start of the Iraq war.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart6.gif
Education. The military's rank structure ensures that the officer
corps is highly educated. By definition, every West Point graduate
or officer with an Army ROTC commission has earned a bachelor's
degree. Overall, 94.9 percent of all officer corps accessions have at
least a four-year bachelor's degree.[13] In contrast, 25.0 percent
of Americans between the ages of 22 and 27 had at least a four-year
bachelor's degree in 2006.[14]
Race. The officer corps' pattern of racial representation differs
from the pattern in the enlisted force. The analysis of the Army ROTC
data compared newly commissioned officers to the college-educated
population 18–27 years old for 2004 to 2006. ROTC race representation
and officer-to-population ratios can be found in Table 4.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_table4.gif
When compared to the relevant population group, whites are roughly
proportionally represented in the ROTC in all four years, similar to
what was observed in the enlisted military population. Blacks are
overrepresented in all four years, but this overrepresentation
decreases in each successive year.
The percentage of Hispanics completing college is roughly equal to
the proportion participating in the ROTC, indicating proportional
representation of this demographic group. This is true of all years,
except 2007 when Hispanics are largely underrepresented in ROTC
programs, with a cadet-to-population ratio of just 0.68. However, the
2007 ROTC numbers should be interpreted cautiously because they
include all current ROTC participants and ROTC cadets who were
commissioned in 2007. These figures may be misleading because they do
not account for attrition among current cadets, and future analysis
may find that Hispanic representation in the ROTC in 2007 was
proportional when compared to Hispanics in the general population
with college degrees. This caveat should be applied to all 2007 ROTC findings.
The proportion of Asians in the ROTC population is smaller than in
the comparison group, indicating that fewer Asians are participating
in the ROTC than are attending and completing college. The percentage
of American Indian and Alaskan natives who participate in the ROTC is
small, but it more than doubled between 2004 and 2005, moving from
being proportionally represented in 2004 to being overrepresented since 2005.
The data on cadets attending West Point do not include information on
race, so race was imputed using census tract demographic information
for each cadet's home of record. The race representation at the
census tract level was computed using Census 2000 data for the
population 18 and older. Chart 7 reports the race results for the
census tracts with at least one USMA cadet along with the overall
observed percentage of adults ages 18 and older by race category.
Based on census tract information from the decennial census, white
and Asian demographic groups are overrepresented in the military
academy population, and all other race groups are underrepresented.
Region.The regional distribution of newly commissioned officers is
similar to the distribution of enlisted recruits. As among enlisted
recruits, the South accounts for 42.5 percent of new Army ROTC
commissioned officers in 2006almost 10 percent above the South's
proportional share. West Point cadets from the South account for 36.7
percent of all 2007 graduates, which is also disproportionally
high. (See Table 5.)
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_chart7.gif
Similar to the enlisted troops, ROTC cadets are underrepresented in
the Northeast. However, the representation of USMA graduates in this
region is proportional. The West is underrepresented in the ROTC and
USMA. The regional representation of the ROTC is smaller than the
comparable population in 2004, but it grows through 2006, when the
West is proportionally represented. The 2007 data suggest an
underrepresentation, but this should be interpreted cautiously for
the reasons mentioned previously. The Midwest is also proportionally
underrepresented among West Point graduates.
Maps 3 and 4 show the representation ratios for each state for 2007
ROTC cadets and USMA graduates. Table A1 in the Appendix shows the
representation figures for ROTC cadets in 2004–2006 for each state.
Conclusion
The men and women who serve in America's all-volunteer military do
not come disproportionately from disadvantaged backgrounds. Instead,
the opposite is true. Both active-duty enlisted troops and officers
come disproportionately from high-income neighborhoodsa trend that
has increased since 9/11.
America's troops are highly educated. Enlisted recruits have
above-average intelligence and are far more likely than their
civilian peers to have a high school degree. Nearly all of the
officer corps has at least a four-year college educationfar greater
than the rate in the civilian population. The racial composition of
the military is similar to that of the civilian population, although
whites and blacks are slightly overrepresented among enlisted recruits.
http://www.heritage.org/Research/NationalSecurity/images/CDA08-05_table5.gif
The popular impression that many soldiers join the military because
they lack better opportunities is wrong. In all likelihood, our
soldiers would have had many lucrative career opportunities in the
private sector. The officers and enlisted men and women of the armed
forces have made sacrifices to serve in the U.S. military.

Technical Appendix
This paper uses data on enlisted personnel and officers and cadets in
the Army Reserve Officers Training Corps (ROTC) and United States
Military Academy (USMA) at West Point. The data were provided by the
Defense Manpower Data Center at the request of The Heritage
Foundation. The troop data included the full home-of-record address
for each recruit, which was used to merge the data with demographic
data at the census tract level from the Census Bureau. Analysis of
the data on enlisted personnel focuses on the demographic
characteristics of troops who reported no previous military service
(non–prior service accessions).
The analysis presented here updates a previous Heritage Foundation
paper with data on U.S. enlisted recruits during 2006 and
2007.[15] In addition, it presents some new analysis on military
officers based on data from 2004–2007 Army ROTC programs and 2007
data on officer commissions from the USMA (West Point).
Populations were compared using data from Census 2000; the 2006
American Community Survey (ACS); and the Integrated Public Use
Microdata Series (IPUMS).[16] All analyses at the census tract level
used data from the 2000 Census because these are the most recent
census tract data available. Statistics reported at the national or
state level used 2006 ACS data or IPUMS data. Since the majority of
new enlisted recruits are between the ages of 18 and
24,[17] comparisons to the general population using Census, ACS, or
IPUMS data were made using this age group when possible.
Recruit Data
The recruitment data from the U.S. Department of Defense consist of
three sets of data: recent enlisted accessions, commissioned officers
from and current participants in the Army ROTC, and recent graduates
from West Point. The enlisted data cover two years of recruits:
non–prior service enlisted accessions from October 2005–September
2006 (2006 data) and from October 2006–September 2007 (2007 data).
The 2006 data cover 166,299 recruits, and the 2007 data cover 158,069
recruits. Each recruit record includes full address information,
race, Hispanic ethnicity, and educational codes. The data include
accessions for the Army, Navy, Marine Corps, and Air Force.
The analysis presented in this paper considers only the demographic
characteristics of the active-duty component of the military. Data on
the Reserve and National Guard recruits were not included.
The Army ROTC data cover four years of ROTC cadets, including
officers commissioned in 2004, 2005, and 2006 and those commissioned
as of March 27, 2007. The data also include information on all cadets
participating in the ROTC in 2007. The data on 2007 commissioned
officers and current ROTC participants were combined into one group
for purposes of analysis. There were 4,408 officer accessions in
2004, 4,178 in 2005, and 4,050 in 2006. As of March 2007, there were
675 officer accessions, and 25,789 cadets were participating in the
ROTC, bringing the ROTC population size for 2007 data to 26,464
cadets. Similar to the enlisted data, the ROTC data included each
cadet's full address, race, and Hispanic ethnicity.
The USMA data cover officer commissions from West Point in 2007. In
2007, 1,011 officers were commissioned from West Point, and the data
include each cadet's home-of-record address.
Race Data
Census race categories allow for any combination of six races
(American Indian or Alaskan Native, Asian, Native Hawaiian or Pacific
Islander, black or African–American, white, and other). The data on
enlisted personnel include race categories that reflected census
coding. The ROTC data included one category for Asian. The census
categories for Asian and Hawaiian and Pacific Islander were combined
in order to compare the ROTC Asian category to the general population.
The enlisted, ROTC, and census data also include Hispanic ethnicity
indicators, and the race categories analyzed in this paper identify
Hispanics as a distinct race group. Therefore, in this
categorization, all other races (e.g., white, black, and Asian) are
represented as non-Hispanic race.
Invalid Recruit Addresses
Address information in each file was used to match each recruit to
his or her census tract using ArcGIS spatial match procedures. In
some cases, the provided address could not be matched to a specific
census tract because it could not be located in the address locator
database supplied by Environmental Systems Research Institute
(ESRI). This occurred most often when the address was a post office
box or general delivery location.
These unmatched records were rematched by Zip code and randomly
assigned to a census tract based on the five-digit Zip. Any remaining
unmatched records were excluded from the analysis. Troops with home
addresses outside of the 50 states and the District of Columbia were
excluded from the analysis.
Census Data
The census data methodology used in this paper is similar to the
methodology used in previous Heritage Foundation reports on troop
demographics.[18] Data were taken from the United States Census
2000, Summary File 1 and Summary File 3, and the United States Census
2004, 2005, and 2006 ACS. The data from Summary File 1 are collected
for the whole population, and Summary File 3 and the 2004 ACS contain
estimates from sample data.
Income analysis for all recruit years used data from Census 2000,
Summary File 3, Table P53 (Median Household Income). More recent data
by census tract are not publicly available.
Educational analysis for the recruit cohorts used data for the
population ages 18–24 from the 2006 ACS Summary File 3, Table PCT25
(Sex by Age by Educational Attainment for the Population 18 Years and
Over), and used the age breakdown in this table to focus on the
population ages 18–24.
Race analysis for the 2004 and 2005 recruit cohorts used data based
on the authors' calculations based on data from the 2004 through 2006
IPUMS data to assess proportionality on a national level, not by census tract.
The regional analysis used data based on the authors' calculations
from the 2004 through 2006 IPUMS data to assess proportionality at
the state and region levels.
The population count for ages 18–24 refers to the estimate of
27,067,510 for Census 2000. The more recent sample data in 2006 ACS
give a sample-based estimate of 29,700,518 for the population ages
18–24. Summary File 1, which is representative of the whole
population for Census 2000, reports the total population 18 years and
over as 209,128,094. The 2006 ACS race reports a sample-based
population estimate of 225,633,342.
Income Analysis
The recruit data did not include any information on recruits'
incomes. The average household income calculations performed in this
paper were done by assigning each recruit the median household
income value in 1999 for his or her census tract. These dollar values
were adjusted for inflation and expressed in 2008 dollars. The income
analysis was weighted by the total population ages 18–24 in each
census tract to adjust for uneven population distribution among census tracts.
Educational Analysis
The educational analysis compared educational attainment of non–prior
service enlisted recruits to educational attainment data of the U.S.
male population ages 18–24 from the 2006 ACS, Table B15001. Due to
inconsistencies in the coding of the education data supplied by the
Defense Manpower Data Center, and in order to match more closely the
official Department of Defense education statistics on the non–prior
service enlisted recruit population, some educational categories
were removed from consideration in the educational analysis.
Race Analysis
The race analysis for the enlisted troops compared the race
distribution of these troops to the race distribution of males 18–24
years old in the general population, calculated using the 2006 IPUMS
data. Similarly, the ROTC race distributions were compared to race
distributions of males 18–27 years old with at least a college
education in the general population, using the 2004, 2005, and 2006
IPUMS data. The 2007 ROTC data included information on currently
enrolled cadets as well as recent accessions and was compared to
males 18–27 years old with at least some college education using the
2006 IPUMS data. The 2006 data are the most recent available and were
used as the point of comparison for both the 2007 enlisted and ROTC data.
Race information for the USMA officer commissions was not available.
Race analysis for this group was conducted by using the race
characteristics of the census tracts where the cadets lived. Once
race was established using census tract information, this group was
compared to the total population 18 and older using Table P6 from
Census 2000 Summary File 1.
Regional Analysis
The census region, census division, and state comparisons in this
paper used the authors' calculations of state population data from
the 2004 through 2006 IPUMS. The IPUMS population varied depending
on the military population being considered.
The population comparison for the 2006 and 2007 enlisted active-duty
military was done using calculations from the 2006 IPUMS data for the
male population ages 18 to 24.
The 2004–2006 IPUMS data for males ages 18 to 27 with at least a
bachelor's degree were used for the comparisons of ROTC
proportionality for 2004 through 2006. The 2006 IPUMS data for males
ages 18–27 with at least some college education were used as the
relevant comparison population for the 2007 ROTC data because these
data included graduates and currently enrolled ROTC participants.
The 2007 USMA population was compared to calculated population
numbers from the 2006 IPUMS for males 18–27 years old with at least a
college education.
