About the Data

The best source of data on Native Lands between 1912 and 1920 are the Annual Reports of the Commissioner of Indian Affairs. The reports from 1912 to 1920 include an acreage Acreage Agency Recapitulation table, broken down by Reservation We have tabulated and made that data availabe in machine Readable format availabe here. For land data between 1966 and 1984 the best source is the BIA’s Annual Report of Indian Lands and the source for this dashboard. The Native Lands Advocacy Project (NLAP) has searched the National Archives and Library of Congress in DC, as well as numerous online databases, and have only been able to find these reports for the following years: 1966, 1975, 1977, 1978, 1979, 1980, 1981,1982, 1983, 1984, and 1985. Each report was manually transcribed by the NLAP and entered into a database.

Why is this Data and Dashboard Important?

Established in 1824, the US Bureau of Indian Affairs is responsible for the administration and management of 55 million surface acres and 57 million acres of subsurface minerals estates held in trust by the United States for American Indians, Native tribes, and Alaskan Natives. Despite this huge responsibility, there is very little transparency or accountability when it comes to the BIA’s performance as trustee. Even basic data about the status and changes in tust assets is difficult to obtain. This lack of transparency makes it difficult, if not impossible to monitor or assess the Bureau’s performance as trustee and protect Tribal resources from waste, fraud and abuse. 

These datasets can be used to track land area totals and lands status changes over time. 

Questions This Dataset Can Help Answer:

  • How many acreas of BIA managed Allotted, Tribal, and Government lands are there on my Reservation, County, and State?
  • How have those acreage totals changed over time?

This data is particularly useful to compare with totals published by your county assessor. 


The data is only as good as what was published by the Bureau of Indian Affairs. County data for Alaska doesn’t exist before 1981. While we do our best to quality check data transcriptions, errors do occur. Doulbe check discrepancies with original printed Annual Report of Indian Lands.
