| a For data before 2003, the 1977 Office of Management and Budget (OMB) Standards for Data on Race and Ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. The revised 1997 OMB standards were used for data for 2003 and later years. Persons could select one or more of five racial groups: White, Black or African American, American Indian or Alaska Native, Asian, or Native Hawaiian or Other Pacific Islander. Included in the total but not shown separately are American Indian or Alaska Native, Asian, Native Hawaiian or Other Pacific Islander, and "Two or more races." Beginning in 2003, those in a given racial category represent those reporting only that race. Data from 2003 onward are not directly comparable with data from earlier years. Data on race and Hispanic origin are collected separately. Persons of Hispanic origin may be of any race. |
| b Due to the small sample sizes, data for Blacks and Hispanics are subject to relatively large sampling errors. |
| c Moving averages are used to produce more stable estimates. A 3-year moving average is the average of the estimates for the year prior to the reported year, the reported year, and the following year. For 2009, a 2-year moving average is used, reflecting an average of the 2008 and 2009 estimates. |
