Priority Populations<br />
Racial and Ethnic Minorities<br />
In 2010, more than one-third of the U.S. population identified themselves as members of racial or ethnic<br />
minority groups (U.S. Census Bureau, 2011a). By 2050, it is projected that these groups will account for<br />
almost half of the U.S. population. The U.S. Census Bureau estimated that the United States had about 39<br />
million Blacks or African Americans in 2010 (12.6% of the U.S. population) (U.S. Census Bureau, 2011a);<br />
more than 47.8 million Hispanics or Latinos (15.5%) (U.S. Census Bureau, 2008); almost 14.8 million<br />
Asians (4.8%); about 6.2 million NHOPIs (0.2%); and nearly 3 million AI/ANs (0.9%) (U.S. Census Bureau,<br />
2011a), of whom 57% reside on Federal trust lands (Smedley, et al., 2003).<br />
Racial and ethnic minorities are more likely than non-Hispanic Whites to be poor or near poor (Lillie-<br />
Blanton, et al, 2003). In addition, Hispanics, Blacks, and some Asian subgroups are less likely than non-<br />
Hispanic Whites to have a high school education (Collins, et al., 2002).<br />
Previous chapters of the NHDR describe health care differences by racial and ethnic categories as defined by<br />
the Office of Management and Budget and used by the U.S. Census Bureau (Executive Office of the<br />
President, 1997). In this section, quality of and access to health care for each minority group are summarized<br />
to the extent that statistically reliable data are available for each group.<br />

Criteria for importance are that the difference is statistically significant at the alpha ≤ 0.05 level (two-tailed<br />
test) and that the relative difference from the reference group is at least 10% when framed positively as a<br />
favorable outcome or negatively as an adverse outcome. Access measures focus on facilitators and barriers to<br />
health care and exclude health care utilization measures.<br />
Changes Over Time<br />
This section also examines changes over time in differences related to race and ethnicity. For each measure,<br />
racial, ethnic, and socioeconomic groups are compared with a designated comparison group. The time<br />
periods range from 2000-2002 to 2008-2010, depending on the data source. Consistent with <strong>Health</strong>y People<br />
2020, disparities are measured in relative terms as the percentage difference between each group and a<br />
comparison group. New this year is the use of a linear regression model to estimate the difference in the<br />
annual rate of change for the comparison group relative to the reference group.<br />
The difference in annual rate of change for the comparison group relative to the reference group was<br />
estimated. Determinations of whether subgroup differences have grown, narrowed, or remained the same<br />
were based on estimated differences in annual rate of change as specified below:<br />
n Subgroup differences are deemed to be narrowing if the change in disparities is less than −1 and p<br />
