Census Block Groups sit in a "mid-range" geography between census blocks and census tracts.
All cover the U.S. wall-to-wall and nest together, census blocks being the lowest common denominator for each.
Block Groups (BGs) are the smallest geographic area for which annually updated
American Community Survey (BG) data are tabulated.
November 2014. Some parts of this section have been updated. See the following updated sections:
Hawaii 2014 GIS Project
Profiles & Reports
API Data Integration
Site Analysis
Advantages of using BG geodemographics include the maximum degree of geographic drill-down ... enabling the
most micro-perspective of demographics for a neighborhood or part of study area.
Among the disadvantages of BG estimates (e.g., from ACS) is that typically the smaller area estimates have a relatively higher error
of estimate. But that is true only of the ACS data, and not the Census 2010 data which are not estimates and have no error
of estimation (though other types of errors may exist).

Use the above table to view/query/rank/compare the distribution of family income by income category
by Census 2010 block group based on ACS 2010 5-year estimates.
Subject matter columns are described below. The data in the ranking table were developed using the ACS 2010
5-Year Estimates Tracts and Block Groups Summary File.

Block Group Mapping & GIS Applications
Ranking the above table on percent families with income over $200,000 (far right column) reveals that Maui tract 030706 block group 2
has 13 families all with income of $200,000 or more.
Using the
GIS Resources HI2012 GIS project, this area is shown in the graphic shown below (by pointer).
This block group is partly in Maalaea CDP and Kihei CDP (split by N Kihei Rd).
Hawaii BGs with the largest number of families with income over $200,000 are in Honolulu: 000402-2 (286),
000402-1 (266), and 000401-1 (204).

The following applications illustrate use of block group geography and demographics in Honolulu County.
These applications are not directly related to data in the above ranking table.
Two thematic maps are shown and a related comparative analysis for selected block groups.
These applications make use only of Census 2010 geography and demographics.

Some notes shown below may not appear in profile depending on geographic selections. [1] Other Asian alone, or two or more Asian categories. [2] Other Pacific Islander alone, or two or more Native Hawaiian and Other Pacific Islander categories. [3] One of the four most commonly reported multiple-race combinations nationwide in Census 2000. [4] In combination with one or more of the other races listed. The six numbers may add to more than the total population, and the six percentages may add to more than 100 percent because individuals may report more than one race. [5] This category is composed of people whose origins are from the Dominican Republic, Spain, and Spanish-speaking Central or South American countries. It also includes general origin responses such as "Latino" or "Hispanic." [6] "Spouse" represents spouse of the householder. It does not reflect all spouses in a household. Responses of "same-sex spouse" were edited during processing to "unmarried partner." [7] "Family households" consist of a householder and one or more other people related to the householder by birth, marriage, or adoption. They do not include same-sex married couples even if the marriage was performed in a state issuing marriage certificates for same-sex couples. Same-sex couple households are included in the family households category if there is at least one additional person related to the householder by birth or adoption. Same-sex couple households with no relatives of the householder present are tabulated in nonfamily households. "Nonfamily households" consist of people living alone and households which do not have any members related to the householder. [8] The homeowner vacancy rate is the proportion of the homeowner inventory that is vacant "for sale." It is computed by dividing the total number of vacant units "for sale only" by the sum of owner-occupied units, vacant units that are "for sale only," and vacant units that have been sold but not yet occupied; and then multiplying by 100. [9] The rental vacancy rate is the proportion of the rental inventory that is vacant "for rent." It is computed by dividing the total number of vacant units "for rent" by the sum of the renter-occupied units, vacant units that are "for rent," and vacant units that have been rented but not yet occupied; and then multiplying by 100. |
