How to Get Congressional District

[M23]

How can I get the congressional district for every state? 

I look for the cd: tag under divisions, which returns for Arkansas in the example below. 

However other states, like Delaware in the example below, are not returning a cd: tag or a congressional district value.

Arkansas

"kind": "civicinfo#representativeInfoResponse",

  "divisions": {

    "ocd-division/country:us/state:ar/sldl:76": {

      "name": "Arkansas State House district 76",

      "officeIndices": [

        1

      ]

    },

    "ocd-division/country:us/state:ar/cd:2": {

      "name": "Arkansas's 2nd congressional district",

      "officeIndices": [

        0

      ]

    },

    "ocd-division/country:us/state:ar/place:little_rock": {

      "name": "Little Rock city",

      "officeIndices": [

        2

      ]

    }

  },

 

Delaware

  "kind": "civicinfo#representativeInfoResponse",

  "divisions": {

    "ocd-division/country:us/state:de/sldl:9": {

      "name": "Delaware State House district 9",

      "officeIndices": [

        1

      ]

    },

    "ocd-division/country:us/state:de": {

      "name": "Delaware",

      "officeIndices": [

        0

      ]

    },

    "ocd-division/country:us/state:de/county:new_castle": {

      "name": "New Castle County",

      "officeIndices": [

        2

      ]

    },

    "ocd-division/country:us/state:de/county:new_castle/council_district:12": {

      "name": "New Castle DE County Council District 12",

      "officeIndices": [

        3

      ]

    }

  },

Hi there,

Looks like you are calling queryRepresentativeInfo, but if you just want a list of districts, you could use divisionSearch instead. 

Example: https://developers.google.com/civic-information/docs/v2/divisions/search?apix=true&apix_params=%7B%22query%22%3A%22%5C%22congressional%20district%5C%22%22%7D#try-it

divisionSearch uses Apache Lucene syntax, so quoting and boolean operators follow those rules. They are documented at https://lucene.apache.org/core/2_9_4/queryparsersyntax.html

You could also find a list of all US congressional districts in the official repository, at https://github.com/opencivicdata/ocd-division-ids/blob/master/identifiers/country-us/census_autogenerated/us_congressional_districts.csv
