API Technical Discussions

How to decode the Variables?

I am looking at the examples of Request URL examples. I am wondering if the Variables follow any structure and if so were I can learn about it. In another words, can those variables be interpreted to what data is requested? If so, is there a document that describe it? Are the letters in the front has any significance/rules, and are the following digits follow any rules? P012D007, B02001_001E, PCT012A015 etc.... ...more »

Bugs / Problems

"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?

In particular, if I execute an identical ...more »

Using Data

Obtaining census tract numbers

Can I use this API to create an easy way for users on my website to get their census tract number without using a map? I simply want the users to input their residential address into text fields. Hopefully this API will spit out their 10 digit census tract number after input. I would prefer NOT to redirect applicants to a 3rd party site. I ultimately want to use the census tract number from the API to reconcile it with ...more »

General Feedback

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?

Feature Requests

School District Type

This is a request to simplify the school district API call structures to have only one replacing the three separate calls for unified, secondary and elementary. The school district codes are unique within state irrespective of the type (U, S, E). Most users are interested in a few districts by name/id, all districts in a state/region or all districts in the U.S. Also, just having the state+district code provides ...more »
