Example 3: Search for Location and Containment Data Request
Updated
by
PolicyMap
Search for a zip code, identify census tracts within, and show data for each tract.
The query string below is used to search for the zip code of 08065, return the census tracts within the zip code, and display the percentage of persons who are Hispanic or Latino in each tract.
ty=data&t=sch,ind&sbt=7&ss=08065&cbt=6&ii=9868944
Definition of parameters in string
- ty: The service type, which in this case is 'data': a JSON string.
- t: The data sub type. A single or comma-delimited set of sub types. In this example; sch=search for a location and ind=data requested.
- sbt: The search boundary type. A single or comma-delimited set of numbers. Required when using the containment boundary type in a search (sch) request. In this example, 7 is the code for zip code tabulation areas.
- ss: The search search string. A free-form URL encoded string or integer representing a FIPS code. In this example, we are searching for the zip code: 08065
- cbt: The containment boundary type. A single or comma-delimited set of numbers. Specifying this parameter causes a request to chain internally and derive all boundaries of this type that are contained* within any boundaries specified in the initial request. (* Only matches if the boundary is 100% contained). In this example; 6=census tracts
- ii: The indicator id(s). A single or comma-delimited set of numbers. In this example; 9868944 is the percentage of persons who are Hispanic or Latino.
Some elements of the original return have been removed to simplify the results displayed here.
Description of the results
The sch (search) sbt=7 (zip code boundaries) ss=08065 identifies the zip code of 08065
The cbt=6 finds the three census tracts inside the zip;
- 34005700102, 34005700103, 34005700104
The ii=9868944 indicator is Percentage of persons who are Hispanic or Latino which shows the values for each tract as;
- 34005700102 = 2.69%
- 34005700103 = 5.67%
- 34005700104 = 10.91%
