Bottom line

• The file gives the directory information of each institution in the 2025 IPEDS Institutional Characteristics data: 5,985 rows, one for each IPEDS unit ID (UNITID).
• Each row gives the name, the address, the city, the state, the county name (COUNTYNM), the latitude (LATITUDE) and the longitude (LONGITUD).
• All 54 California institutions with a 2025 Carnegie Research Activity Designation have a row, with a county, a latitude and a longitude.

Background

NCES, in the U.S. Department of Education, runs IPEDS, the federal data collection for postsecondary institutions. The HD file is the directory part of the Institutional Characteristics survey. NCES gives it as a zip file with one CSV file in it. It is a work of the U.S. Government, so the library rehosts it.

Key claims

• The header row of hd2025.csv starts “UNITID,INSTNM,IALIAS,ADDR,CITY,STABBR,ZIP” and ends “COUNTYCD,COUNTYNM,CNGDSTCD,LONGITUD,LATITUDE”. (hd2025.csv, header row)
• Row 110671: “110671,University of California-Riverside,UC Riverside,900 University Ave,Riverside,CA,92521”, with COUNTYNM “Riverside County”, LONGITUD “-117.327410” and LATITUDE “33.972460”. (hd2025.csv)
• Row 243744: “Stanford University”, city “Stanford”, COUNTYNM “Santa Clara County”, LONGITUD “-122.167359” and LATITUDE “37.429434”. (hd2025.csv)
• Row 445188: “University of California-Merced”, city “Merced”, COUNTYNM “Merced County”, LONGITUD “-120.424944” and LATITUDE “37.366237”. (hd2025.csv)

Evidence and method

• Federal administrative data that institutions report to IPEDS. The file has 70 columns.
• Other columns give the chief administrator, the web addresses, the sector, the control, the Carnegie codes and the core-based statistical area.
• LATITUDE and LONGITUD are decimal degrees with six decimal places.
• 664 rows have the state CA.
• The library’s count: all 54 California unit IDs with a designation in the Carnegie 2025 Public Data File (web) are in this file. For each of the 54, the name and the city are the same in the two files.
• The Markdown copy renders the whole CSV file as one table, about 4.5 MB.

Limits

• The file gives one point for each institution. It does not give the location of other campuses, medical centers or field stations.
• The file does not say how NCES got the latitude and longitude.
• The file does not list the national laboratories, because they are not postsecondary institutions.
• The file is for the 2025 data year. A later file can change values.
