ACS data for zip code tabulation area

Hi all,

I am trying to use the api to collect information for zip code tabulation areas from the ACS 2011 survey.

I have tried several variations of the following url, but get an unsupported/unknown geography error:


I have read elsewhere on this form that the 2011 ACS is now available via the API by zip code. Is this correct? If so, what is the proper format to query the API for the ACS survey?

    A quick search through the documentation located at http://api.census.gov/data/2011/acs5/geo.html

    reveals that Zip Code Tabulation Areas do not roll up to state in this dataset.

    You simply have too many parameters, state is not required when addressing ZCTAS in this particular dataset.

    Thus a query structured as below, should retrieve the data you desire.


    Hope this helps you in your use of the API.
