Census Block, Block Group & Census Tract GeoDemographics

Census tracts, block groups and blocks are the important small area statistical geographic areas for which data from Census 2010 are tabulated. Data for census tracts and block groups are also tabulated annually from the American Community Survey. For example. in December 2018, we will have new “richer demographics” annual estimates centric to each year 2008 through 2015 for Census 2010 tracts and block groups … data such as educational attainment, language spoken, housing and household characteristics,  income characteristics and employment and other demographic-economic attributes.

Largest Population New York City (NYC) Census Blocks
The following graphic shows the NYC Census 2010 census block having the largest Census 2010 population that is not a group quarters population block. The Lincoln Center census block shown in the graphic (red boundary) has 4,067 population and 2,922 housing units.

This block (36 061 015500 6000) occupies 0.033 square miles. It has a population density of 122,333 (population per square mile). The NYC block with the largest population is on Rikers Island and has a group quarters population of 8,634 and 0 housing units. For Census 2010, there were 350,169 census blocks covering the state of New York; 13,356 census blocks were water blocks. For the State of New York, as of Census 2010 the average census block population was 55 (57 excluding water blocks).

Census 2010 and Census 2020
These geographies have generally stable geographic areas and codes from one decennial census (e.g., Census 2010) to the next (e.g., Census 2020). Many of these areas will change in terms of code and area for Census 2020, though the geographic changes will typically be small or not at all.

Census 2020 block, block group and tract codes and geometry will be available in late 2020. Initial block level demographics will be available in March 2021.

Census 2010 & Current GeoDemographics
These areas cover the U.S. from wall-to-wall and generally non-changing in terms of boundary and geographic code (geocode) until Census 2020. This section provides a summary of new Web pages with more detail about each of these geographies:
census tracts and tract codes .. 73,056 areas
census block groups and block group codes .. 217,740 areas
census blocks and block codes .. 11,078,297 areas

Each of these pages provides an interactive table to view tallies of Census 2010 for each of these small area geographies.

Combining Address Data with Small Area Geography
The address of the Office of the California Secretary of State, located at 1500 11th St, Sacramento, CA 95814, was geocoded using the APIGeocoder and converted into a shapefile for Geographic Information System applications.  The location is shown as a red marker in the map views shown below, illustrating each type of small area geography: tracts. block groups and blocks.

Census Tracts
Tracts are labeled with green tract codes. Address 1500 11th St, Sacramento, CA 95814 is shown by red marker.  The address is in tract 06067001101.

Is the tract code 11.01 or 001101?
Both. Census tracts within a county are identified by a 4-digit basic code between 0001 and 9999, and may have a 2-digit suffix ranging from .01 to .98; for example, 6059.02. The decimal point separating the 4-digit basic tract code from the 2-digit suffix is shown in Census Bureau printed reports and maps. For geo-referencing, the decimal point is implied and does not appear; the 6-character tract code with lead zeroes is used — a character string with no blanks and all numbers.

Accessing and Using these Geographies & Related Demographics
There are several ways these geographies can be used.
• The geocodes are the “handles” to access demographic-economic statistical data.
• The geographies may be visually, geospatially, related as shapefiles.
.. the Census Bureau makes these shapefiles available for use in user appications.
.. the shapefiles typically do not include demographic-economic data.

Largest School Districts Enrollment Characteristics

..  while school district enrollment is reported by school districts, only public school enrollment is reported. Public and private school enrollment are available by district from the American Community Survey (ACS 2015).  With few exceptions, school districts do not report on demographic-economic characteristics of the school district.  These data are only available from ACS. See the related interactive table to access and compare enrollment characteristics of school districts of interest.

In 2015, there were 1,016 school districts with total population of 65,000 or more (of total 14,650) for which “1-year estimates” were tabulated.  These estimates are based on respondent data for calendar year 2015.  This section summarizes selected enrollment characteristics of the largest districts and provides access to much more detail for each of these districts.

Data Analytics & API Applications

Possibly the most well known APIs (Application Programming Interface) are the Google APIs. Among these, the Google Maps API, or its use, might be the most familiar. See about integrating political/statistical geography and Google Maps API. This section reviews different types of APIs.

Data Analytics and APIs
API technology/tools play an important role in accessing and integrating geographic, demographic and economic data. APIs offer two types of benefits. For Web-based applications, APIs provide the ability for on-the-fly access to selected demographic-economic buried in otherwise large datasets that typically otherwise involve downloading and preprocessing. A second important benefit/use is to extract data from those same datasets, reconfigure the structure of the data retrieved by API and create a new dataset structure that lends itself to analytical applications.

ProximityOne Data Analytics sessions review purpose, scope, strengths, advantages & limitations of APIs described in this section. Topics included in the related Web section include:
Federal Geographic-Demographic-Economic Data Access Using APIs
REST APIs
Federal Communications Commission
Bureau of the Census … much more than Census
Bureau of Economic Analysis
Bureau of Labor Statistics
Data Access & Analytics Applications
There are hundreds more APIs available from Federal agencies and wide-ranging sources.

Using APis and GIS: Visualizing Patterns; Geospatial Analysis
The following graphic has been developed first using API tools to create the underlying datasets. While the source data used in this application could have been downloaded and processed in legacy manner, the API tools provide on-the-fly development of the data in a structure required by the GIS software. These data are then integrated into shapefiles for use with the GIS software. Once the datasets are developed, they can be used in a myriad of application, GIS and otherwise.
