House Office Expenditure Data
Members of the House of Representatives get an annual budget for their Washington and district offices, but how they spend it is up to them. There are some rules: It can’t be used for personal or campaign expenses, and there is no reserve source of money if lawmakers spend all of their allowances.
Lawmakers also are required to report the recipients of their office spending, and since 2009 the Sunlight Foundation has been taking the PDF files published by the House and converting them into text files useful for analysis and research. ProPublica has taken over both the collection and hosting of these files. They can be examined using spreadsheet or database software. You can download the files from this page.
How We Collect This Data
Each quarter we take the report published by the House and generate two text files: One contains summary information for each office and category of spending (some examples include “Personnel Compensation” and “Travel”), and the other contains details of each recipient of office spending and its purpose. Note that the data has not been standardized (meaning that "AT&T" might also appear as "A.T.&T."), so simple aggregation on the recipient could result in multiple totals for the same individual or entity, depending on the spelling. Individual recipients can be paid by more than one office or lawmaker in some cases.
Most of the records are connected to lawmaker offices, but the files also contain spending records for House committees and administrative offices, in addition to leadership organizations such as the Speaker of the House and the two parties' leaders.
