To help local governments better plan for disaster recovery for their residents, it would helpful to know which areas contained high risk/vulnerable individuals. These individuals might include the elderly, small children, disabled individuals, those who are language isolated, and those who do not have access to a vehicle.

Using Data

Problem with List of State Codes and Zip Code Search

I'm trying to retrieve the population for a certain zip code. What I found in your online documentation is that I should use the following URL string: http://api.census.gov/data/2010/sf1?key=(key)&get=P0010001&for=zip+code+tabulation+area:(zip)&in=state:(state) ...where (key) is my API key, (zip) is the zip code, and (state) is a two digit code that you use to identify states.

Using Data

List of all Legislature District "names"

I need a list of all the states' legislature's district names. I will use this list as the definitive list of district names that data is mapped to. I tried to use the " Census Name Lookup Tables" found here: https://www.census.gov/geo/maps-data/data/nlt.html but there are many district names that don't map properly to the district names returned by the 2012-5yr-ACS API. So, for example, if I submit the query: http://api.census.gov/data/2012/acs5?get=B19301_001E&for=state+legislative+district+(lower+chamber):*&in=state:50 ...more »

Access Micro-data for Blocks

I'm working on a school project with 2010 Census data. Currently, we are getting tract-level data using codes from http://api.census.gov/data/2010/sf1/variables.json to get data. For example, to find the white 65-year old males in a county's tracts, we make the API call: http://api.census.gov/data/2010/sf1?key=[key]&get=PCT012I068,NAME&for=tract:*&in=state:08+county:059 However, when making the same call at a block ...more »

Are the letters in the front has any significance/rules, and are the following digits follow any rules? P012D007, B02001_001E, PCT012A015 etc.... ...more »

"Get" argument for API call: is there a length limitation?

I have an API request where the get argument that works is "P0030001,P0030002,P0030003,P0030004". However, I wanted to get all available names in that concept, which in total is a list of 8 elements "P0030001,P0030002,P0030003,...P0030008".

This request fails with error "unknown variable 'P0030005,P0030006,P0030007,P0030008"

Is there a limit on the length for the GET argument?

Support for more geographies in ACS

Is there any support (yet?) for congressional districts and other lower-level geographies in the ACS API? States and counties work fine, but I run into problems as soon as I start to go a little deeper into the hierarchy. Are most of these other area types only supported for the SF1 data?
