This index measures the homogeneity of race in a Census Block Group. The measure does not tell which race is the dominate group, and you need to rely on the actual race data to make that determination. This index includes the ethnic class Hispanic as a separate class in its determination.
Diversity is a function of both the percentage represented of each group and the number of groups represented. The Index can take on a value of 0 to 1, where 1 indicates there is only one race (or ethnic group) represented in that block group. The closer to zero the score is, the more diverse the geographic area is. The Diversity Index is a quick way of determining the level of racial/ethnic diversity of a defined geography.
The data is reported by the following categories:
Population Racial/Ethnic Trends
Population by Racial/Ethnic Trends presents five different racial or ethnic categories. It includes three data points. It is a fairly typical practice to provide a high level variable called "Race/Ethnicity" that rolls up some of the smaller ethnic groups and includes Hispanic or Latino.
People can indicate any race and also Hispanic or Latino. To create this specific report, the racial groups (White, Black/African American, Asian, Pacific Islander/American Indian/Alaska Native/Other/Some other race and two or more races) are reported as "alone" allowing those persons to be reported separate from those who did indicate Hispanic or Latino.
You can generate a Hispanic/Latino category within the Race/Ethnicity report without double counting.
Hispanic or Latino
Black/African American (Non-Hisp)
Pac Is/Am Ind/Alaska Nat/Oth (Non-Hisp)
Population: Asian Alone
The Asian Alone variable reflects the self-identification among people of Asian descent.
Chinese, except Taiwanese
Population by Ancestry
Ancestry data represents self-classification by people according to the ancestry group or groups with which they most closely identify. Ancestry refers to a person's ethnic origin or descent, ''roots,'' heritage, or the place of birth of the person, the person's parents, or their ancestors before their arrival in the United States.
Not all respondents completed this field. As a result, most Ancestry reports create a large group on "Ancestry Unclassified."
Native American (Indian/Eskimo)
Other European (e.g. Greek/Russian)
South Central Asian (e.g. Indian)
South East Asian (e.g. Vietnamese)
Note: Puerto Rico is not included.
Population: Hispanic or Latino by Origin
The terms ''Spanish,'' ''Hispanic origin,'' and ''Latino'' are used interchangeably. Some respondents identify with all three terms, while others may identify with only one of these three specific terms.
Hispanic or Latino Origin can be viewed as the heritage, nationality group, lineage, or country of birth of the person or the person's parents or ancestors before their arrival in the United States. People who identify their origin as Spanish, Hispanic, or Latino may be of any race.
Other Hispanic or Latino
Population 5+ by Language Spoken at Home
Language spoken at home is for the population five (5) years of age and older and reflects the language of the home environment. Two reports are provided, a summary of the major groups and a detail report with the sub-groups. A single data year is given.
Speak only English
Spanish or Spanish Creole
