Navajo Nation Demographic Analysis

Introduction

This analysis of the Navajo Nation was undertaken by the Arizona Rural Policy Institute (ARPI) in the W.A. Franke College of Business at Northern Arizona University for the planning department of the Navajo Nation. The ARPI has produced the Demographic Profile for Navajo Nation with the latest information available from the 2010 Census and the 2010 American Community Survey (5-year estimates). This document is provided to Arizona tribes as a product of the EDA Technical Assistance Grant provided to the ARPI at Northern Arizona University.

Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, it is the Census Bureau's Population Estimates Program that produces and disseminates the official estimates of the population for the nation, states, counties, cities and towns and estimates of housing units for states and counties. Therefore, this report incorporates two major data sources. First, the official 2010 Census, primarily from the SF1 data report to produce data on the population, age, race and ethnicity relative to Navajo Nation. The second data source is the American Community Survey, 5-year estimate data for the period 2006 to 2010 and is annotated in the document as ACS 2010 (5-year estimates). The 2010 ACS 5-year estimates are based on data collected between January 2006 and December 2010. The data were used to analyze household income, poverty rates, employment, language use and household characteristics for Navajo Nation. Only the 5-year estimates are used as the data was provided for small geographic areas, representing the average characteristics over the 5-year period.

The analysis of demographics for the Navajo Nation first examines the 2010 Census and then the American Community Survey where data is available. Demographic characteristics for the Navajo Nation are outlined in three state partitions for Arizona, New Mexico and Utah. Comparisons between the state partitions serve to provide further levels of comparison when examining demographic characteristics of the tribe.

Appendix A contains official Census 2010 data and Appendix B contains American Community Survey data (5-Year Estimates) and Appendix C contains the margin of error estimates to be used to calculate the estimates for the American Community Survey data.

Population

The population of the Navajo Nation saw a slight decrease in population (-3.9%) on tribal lands in 2010 when compared to 2000. New Mexico tribal lands saw the largest decrease in population (-5.7%), followed closely by Utah (-5.0%). Arizona, which has the largest tribal population of the three states, saw a more modest decrease of -2.7 percent. This decrease in tribal members, however, may not truly reflect the actual change in the tribal population between the census periods. The SF1 census is considered the official count, and accounts for only the population within the exterior boundaries of the tribal lands or nation.

Gender

Differences in population between females (50.9%) and males (49.1%) on the Navajo Nation are slight. Female gender ratios on the Navajo Nation are higher in all states. Females (51.0%) comprise a slightly larger proportion of the population among New Mexico tribal members than either of the other states Arizona (50.8%) and Utah (50.1%).

Age

The Navajo Nation is dominated by those under 18 years of age. The under-18 age population accounts for one third (33%) percent of all tribal members. The Utah portion of the Navajo Nation has the largest percentage of the population under age 18 (36%), followed by Arizona (34%) and new Mexico (32%). The fact that one-third of tribal members are younger than 18 years of age carries with it important policy implications. The large portion of younger tribal members influences the provision of health and educational services as well as poverty and workforce issues as well.

On the other hand, the tribe has fewer members who are 65 years or older as a proportion of the total population. This age group, those who have retired and are out of the workforce, account for one-tenth (10.0%) of tribal members. Overall the Utah portion of the Navajo Nation has fewer members over 65 (9%) and more members under 18 years. The Navajo Nation has a similar age profile to other Arizona tribes, with large percentages of tribal members under age 18. Overall,, those age 18 to 64 years account for 57 percent of tribal members, just lower than the portion of the Arizona State population (60.7%). The large number of tribal young persons will have an effect on the development of the tribal workforce in the future. See Table 3, and Figure 2.

A population pyramid, also called an age structure diagram, is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing.

The population pyramids below (Figures 3, 4,and 5) illustrate the difference between male and female 5-year age cohorts for the Arizona, New Mexico and Utah portions of the Navajo Nation. At the top of the age pyramid there are generally more females than males, which is true for the overall population as women tend to live longer than men. Both males and females in the 20-25 age cohorts are missing from the count. The age pyramid provides an illustrated snapshot of the age structure of tribal members at the time of the 2010 census.

Population Under 19 Years

Children under 19 years of age account for 37.4 percent of all tribal members. There are 85,316 males and 88,351 female tribal members, and of these 38.4 percent are males are under age 19 and 36.3 percent are females under age 19. There are generally equal numbers of males (28.3%) and females (28.2%) under age 5; sex ratios are also similar for those between 5 and 10 and 11 to 17 years of age. See Table 4.

Median Age

The median age (point that splits the population where 50% are above and 50% are below) for the Navajo Nation tribal members is 28 years, with males and females aged 27 and 30 years respectively. The median age of tribal members is lower than the state of Arizona (36 years), emphasizing once again the younger age profile of the Navajo Nation. See Figure 6.

Race

Not surprisingly, the majority of the Navajo Nation tribal members identify themselves as American Indian or Alaska Native alone (96%), while the remaining 4 percent are split between white alone (2%), and multi-race persons (2%). This stands in strong contrast to Arizona, for example, which is 73 percent white alone. See Table 6.

Ethnicity

In terms of ethnicity, the vast majority of Navajo Nation tribal members (98%) self-identify as not Hispanic or Latino; only two percent self-identify as Hispanic or Latino. This is much different from the State of Arizona which was almost one-third Hispanic or Latino (29.6%) in the 2010 Census. See Table 7 and Figure 7.

Households

In 2010, there were 49,946 households on the Navajo Nation, with an average household size of 3.5 persons and an average family size of 4.1 persons as well. The average household size of the Navajo Nation (3.4 persons) is larger than the State of Arizona (2.6 persons) as is the average family size for tribal members (4.1 persons) compared to the state of Arizona (3.2 persons). Household size data for Navajo Nation is similar across all three states. See Figure 8.

The next portion of this analysis concerns households and their structure. The Census defines a “household” as a person or group of people who occupy a housing unit. The “householder” is a person in whose name the housing unit is owned, being bought, or rented. A “family household” consists of a householder and one or more people living together in the same household who are related to the householder by birth, marriage, or adoption — it may also include people unrelated to the householder. If the householder is married and living with his/her spouse, then the household is designated a “married-couple household.” The remaining types of family households not maintained by a married couple are designated by the sex of the householder. A “nonfamily household” consists of a person living alone or a householder who shares the home with nonrelatives only; for example, with roommates or an unmarried partner.

Family households (76%) dominate on the Navajo Nation, although traditional married couple families are in the minority (39%), which is lower than the State of Arizona overall (48%). Households headed by a female (single moms) account for one-fourth (26%) of all Navajo Nation households. Two-thirds (65%) of all households are either married couple families (39%) or households headed by single mothers (26%). Other household structures include non-family households (24%), the majority of whom are unmarried partner households (9%). See Table 8 and Figure 9.

Unmarried partner households (9%) occur at a higher rate on the Navajo Nation than in the State of Arizona (8%). Households with a member over age 65 account for one-fifth (22%) of all households, occurring at a lower rate than the State of Arizona (26%). Finally, tribal households are more likely to be headed by a single mother with their own children under age 18 (12%), a higher rate than the State of Arizona overall (7%).

Family households dominate among Navajo Nation tribal members (76%), compared to 66 percent for the State of Arizona overall. Non-family households account for one-fourth (24%) of tribal member households, less than the State of Arizona (34%). Husband and wife families account for half (52%) of households, less than the State of Arizona where households are 73% as likely to consist of husbands and wives. Households on the Navajo Nation (26%) are two twice as likely as the State of Arizona (12%) to be headed by a single mother. Households on the Navajo Nation are more likely (49%) to have children under the age of 18 living in the household, than the State of Arizona generally (34%). Households headed by single mothers are comparable for Navajo Nation populations in the three states. See Table 10 and Figure 11.

Children Under 18 Years Age Living with Grandparent

Children under age 18 are four times more likely to live with grandparents on the Navajo Nation (8.6%) than they are, for example, in the State of Arizona (2.3%). There are few differences between the proportions of children by age living with grandparents, when comparing the Navajo Nation populations in Arizona, New Mexico or Utah. See Table11 and Figure 12.

Presence of Multigenerational Households

Households on the Navajo Nation are three times more likely to be multi-generational (14.7%), than they are, for example, in State of Arizona overall (4.9%). The Census defines multi-generational families as family households consisting of more than two generations, such as a householder living with his/her children and grandchildren. Multi-generational family households may be more likely to reside in areas where new immigrants live with their relatives, in areas where housing shortages or high costs force families to double up their living arrangements, or in areas that have relatively high rates of out-of-wedlock childbearing. The data show that multi-generational households on the Navajo Nation are more common in New Mexico and less common in Utah; Arizona is right at the average. See Figure 13.

Household Income

The median household income for the Navajo Nation is $27,389, which is approximately half that of the State of Arizona ($51,310) overall. One-third (32%) of all households on the Navajo Nation have incomes of less the $15,000 when compared to the State of Arizona (17%). Tribal members have the same proportion of incomes between $15,000 and $35,000 (28%), a rate that is slightly higher than the State of Arizona (22%). Only small percentages (13%) of tribal members have incomes in excess of $75,000. Few differences appear in the data on household income for Navajo Nation populations across the three states.

Poverty

Poverty rates on the Navajo Nation Reservation (38%) are more than twice as high as poverty rates in the State of Arizona (15%). Almost half (44%) of all children under 18 years of age are considered to be living in poverty, while one-third (34%) of tribal members between 18 and 64 also live in poverty. Almost one-third (29%) of persons living in families on the Navajo Nation live in poverty, twice the rate of families living in poverty in the State of Arizona (13%), for example. More than one-third of all persons over age 65 (39%) also live in poverty, five times higher that the State of Arizona (8%) for this age group. Poverty rates are consistent for Navajo Nation tribal members residing in all three states. See Table 15 and Figure 16.

Households in Poverty

The Census Bureau uses a set of money income thresholds that vary by family size and composition to determine who is poor. If a family’s income is less than a family’s threshold, then that family and every individual in it, is considered poor. Further the ratio of income to poverty can be used to measure the degree or depth of poverty. The ratio of income to poverty compares a person’s income with their poverty threshold, and expresses the comparison as a fraction. For example, a poverty ratio of 1.0 (income at 100% of poverty level) means a person is living right at the poverty line; a ratio of 0.5 (income at 50% of poverty level) would mean that a person is living in a household making only half the income designated as the poverty threshold. The Census Bureau describes those with family incomes below one half of their poverty threshold as being “severely poor.” People with incomes at or above their threshold but below 125 percent of their threshold are classified as “near poor.”

More than one-third (38%) of the Navajo Nation tribal members are classified as “severely poor,” with poverty ratios that ranges from below 0.5 to .99. These rates are more than twice as high as those of the State of Arizona (15%). A further 29 percent of tribal members are classified as above the poverty line with poverty ratios between 1 and 2. The data indicates that more than one-third (38%) of households are below the poverty line, while the remaining 62 percent are located above the poverty line. Again, data are consistent for tribal members across the three states. See Table 16 and Figure 17.

APPENDIX C: THE NAVAJO NATION AMERICAN COMMUNITY SURVEY 2010, 5-YEAR ESTIMATES and MARGIN OF ERROR ESTIMATES

ACS Margin of Error Estimates The ACS estimates are based on data from a sample of housing units and people in the population, not the full populations. For this reason, ACS estimates have a degree of uncertainty associated with them, called sampling error. In general, the larger the sample, the smaller the level of sampling error. The ACS calculates standard errors for each estimate produced and publishes the 90 percent confidence level margins of error (the Census Bureau standard). You can be 90 percent confident that the interval within the margin of error from the estimate includes the true value. Users can add and subtract the margin of error value from the estimate to find the top and bottom of the range within which the ACS is 90 percent confident in their estimate lies.

Understanding margin of error A term you will often come across in survey research is "within the margin of error." Most people hear the term frequently during election season when results from polls are reported. Many surveys and polls collect data from a representative sample of a population to make determinations about a larger population. Results would be somewhat different each time the survey is administered to a different representative sample. The margin of error accounts for these differences by calculating an upper and lower boundary the true result would likely fall between if every member of population was surveyed.

For example, in the case of the Navajo Nation the ACS has established that the median household income (the point at which 50% of households are above and 50 % of households are below) is $26,232. The estimates also indicate that the margin of error of plus or minus (±) $988 percent at a 90 percent confidence interval. The margin of error tells us that if the same survey were administered to the Navajo Nation members again, it is highly probable that the median income would be $25,244 and $27,220 or the median household income ($25,232) ± $988.

Explanation of Symbols: 1. An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate. 2. An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution. 3. An '-' following a median estimate means the median falls in the lowest interval of an open-ended distribution. 4. An '+' following a median estimate means the median falls in the upper interval of an open-ended distribution. 5. An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open-ended distribution. A statistical test is not appropriate. 6. An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variability is not appropriate. 65

7. An 'N' entry in the estimate and margin of error columns indicates that data for this geographic area cannot be displayed because the number of sample cases is too small. 8. An '(X)' means that the estimate is not applicable or not available.
