New Data Available at Yale
|
- Thanks to an ongoing project within the department of Economics, Yale has recently received The Integrated Public Use Microdata Series (IPUMS) Complete Count Census Data. These microdata from the decennial US census records from 1870-1950 are the result of collaboration between IPUMS and the nation’s two largest genealogical organizations—Ancestry.com and FamilySearch—and provides a rich source of individual level and household data. Researchers wishing to use the data at Yale must first have their projects approved by iPUMS.
- Jacob Wallace and Chima Ndumele’s SCALE Lab has acquired data from Managed Markets Insight & Technology (MMIT), which can now be used by other researchers. It provides historical (2017-2022) pharmacy and medical benefit coverage information across thousands of health plans, pharmacy benefit managers (PBMs), and payers in the United States. The data include information on state, plan, covered lives, product class (per the First Databank Compendium), drug name, formulary placement, and utilization management requirements. MMIT receives its data directly from primary documentation, payers, and pharmacy benefit managers, enabling a more complete depiction of Medicaid formulary data than publicly accessible documents alone, and covers 98-99% of all covered lives.
- Yale Library maintains a subscription to Dewey Data Inc., a platform that offers access to nearly 20 research datasets. Recently, Dewey has added several datasets including data from:
LobbyingData.com, a provider of real-time and historical U.S. lobbying data, offering coverage of federal lobbying activity from 1999 to present. This newly available dataset includes details on over 1.6 million lobbying contracts, 13,000+ lobbying firms, 200,000+ total entities, and 78,000+ lobbyists. It provides insight for research on policy influence, political economy, and corporate strategy. LobbyingData's proprietary algorithms extract 44+ attributes from government documents, and all publicly traded entities are mapped to ticker symbols for easy integration with financial data.

New Publicly Available Data
|
HDMA Lender File
For many years, researchers have used data collected under the Home Mortgage Disclosure Act (HMDA) to study the mortgage market and other related topics. The Consumer Finance Institute at the Federal Reserve Bank of Philadelphia recently launched a new web page featuring the HMDA Lender File, also known to researchers as the Avery File. This auxiliary data set, created by economist Bob Avery and now hosted by the Philly Fed, provides information on lenders who filed HMDA data between 1990 and 2024. The data can be connected to publicly available HMDA data released by the FFIEC and CFPB to better understand lender characteristics and to track mortgage applications and originations across lender subsidiaries and over time. The background and history of this file is described here.

Why Data Drive?
The title is a nod to both the hard drives of computing's past — and a reflection of our love of disc golf. Just like in the game, we hope this newsletter finds its mark and lands close to the target.
