Result Files
AP VoteCast subscribers who receive VoteCast data via Elections API will receive results as separate files for each state and the national survey. The files are provided in the JSON format, using a standard file name convention. Each state survey and the national file use the same overall JSON schema. Each file has a header section that includes details on the file’s survey results, the state where each survey was conducted, how many interviews are in the survey and more.

To request AP VoteCast result file updates, use the 'next request' links (see Receiving Election Updates). The list of result files returned when you submit a new API request for VoteCast files always includes links to the latest available versions of the files. The latest version of each result file is always available at the same URL. |

ImportantData Point Variables
Variables that identify data points such as office type (for example, "President" or "Senate") and race type (for example, "G" for general election) correspond to the values used by the Elections API method, which delivers AP vote count. In all cases possible, codes, labels and variables are shared between AP VoteCast and the AP vote count returned by the Elections API method.
Survey Questions
Each AP VoteCast survey will share the same core set of questions. There is also some variation between surveys, as questionnaires are designed to match the differences in populations and news in each state. A final version of the survey questionnaire will be provided when complete, about a week before Election Day. Draft versions of the questionnaire will be used to generate test data.
National Survey Data
The national survey data cannot be filtered by state. State survey results cannot be filtered into smaller, specific geographic units such as county or congressional district. All survey result values should be rounded to whole numbers.
