Indiana Property Data for Academic Research
3.7 million parcels with multi-year assessments, sales records, and building characteristics for research in housing, tax policy, and urban planning.
The problem
- Academic researchers spend months collecting data from county websites
- Data format varies between counties, requiring extensive cleaning
- Historical assessment data is difficult to obtain programmatically
- Spatial analysis requires separate GIS data acquisition
