The Repatriation Database Data from Nov. 29, 2023

According to a June 2023 California state audit, this institution is one of twelve California State University campuses that do not know the extent of their collections of Native American remains and items. Therefore, the reported number of remains and items is likely incomplete.

Sonoma State University

Located in California

Sonoma State Univ. has the 58th largest collection of unrepatriated Native American remains in the U.S. The institution reported still having the remains of at least 200 Native Americans that it has not made available for return to tribes.

The institution has made available for return 54% of the more than 500 Native American remains that it reported to the federal government.

remains of 315 Native Americans made available for return to tribes

remains of at least 267 Native Americans not made available for return

Where Native American remains reported by Sonoma State Univ. were taken from

Each county is a peak

Height is the minimum amount of remains taken from county, as reported by institution

Color is reported rate of remains made available for return to tribes

Institution reported no remains taken from these counties

Location of institution

Under the Native American Graves Protection and Repatriation Act, when an institution establishes a connection between tribes and remains, it must publish a list of the tribes eligible to make a repatriation claim. The remains are then made available for return to the tribe(s). Once a tribal claim is made, physical transfer may occur. Many remains have been physically returned to tribes, but data on this is spotty because the law does not require institutions to report when these transfers occur.

Timeline of Native American remains made available for return to tribes by Sonoma State Univ.

Tribal and institutional capacity, funding, staffing, regulatory changes, audits, Review Committee decisions and litigation may influence timelines. Under NAGPRA, institutions determine whether Native American remains may be returned through cultural affiliation using evidence such as tribal traditional knowledge and biological and archaeological links, or through disposition based on geographic affiliation.

How Sonoma State Univ. compares to other institutions

The amount of Native American remains still held by institutions ranges widely.

Sonoma State Univ. made Native American remains available for return to seven tribes.

Institutions often make remains available for return to multiple tribes, so the amount of remains listed below may be counted for more than one tribe.

Tribe	Remains Made Available for Return To
Federated Indians of Graton Rancheria, California	164
Elem Indian Colony of Pomo Indians of the Sulphur Bank Rancheria, California	113
Middletown Rancheria of Pomo Indians of California	113
Scotts Valley Band of Pomo Indians of California	113
Round Valley Indian Tribes of the Round Valley Reservation, California	22
Kletsel Dehe Wintun of the Cortina Rancheria	16
Yocha Dehe Wintun Nation, California	16

Sonoma State Univ. reported making 60% of more than 13,500 associated funerary objects available for return to tribes.

The funerary objects were taken along with Native American remains reported by the institution.

8,130 associated funerary objects made available for return to tribes

at least 5,465 associated funerary objects not made available for return

About the Data

This tool presents a dataset maintained by the National Park Service containing all the Native American human remains and associated funerary objects that institutions have reported to the federal government under the Native American Graves Protection and Repatriation Act. The dataset includes information about the state and county where remains and objects were taken from, which institutions hold them and whether they have been made available for return to tribes.

The data is self-reported by institutions. The amount of unrepatriated Native American remains reported by institutions is a minimum estimate of individuals and institutions frequently adjust these numbers when they reinventory groups of remains. Some institutions that are subject to NAGPRA have also entirely failed to report the remains in their possession. As a result, the numbers provided are best taken as estimates. The actual number and geographic scope of what’s held by publicly funded institutions is larger than what is presently documented.

ProPublica supplemented this dataset with information about cultural affiliation and disposition to specific tribes by systematically parsing the text of Notices of Inventory Completion published in the Federal Register. An additional dataset from the Department of Housing and Urban Development, the Tribal Directory Assessment Tool, was used for the section on remains not made available for return from counties that each tribe has indicated interest in to the federal government.

Institution location and tribal headquarters location information was provided by National NAGPRA. The location of some groups that are not federally recognized was provided through research by ProPublica.

Institutions that are part of a larger entity are grouped. (For example, the Mesa Verde National Park is part of the U.S. Department of the Interior.)

Institutions that have not submitted information to the federal government are not listed. The Smithsonian Institution is not listed because its repatriation process falls under the National Museum of the American Indian Act and it is not required to publicly report its holdings with the same detail as institutions subject to NAGPRA.

If you work for an institution and would like to provide comment on your institution’s repatriation efforts, please email [email protected]. If you think the data is incorrect or have a data request, please get in touch. We are aware of some issues with the accuracy of location information and tribes mistakenly being identified for disposition of Native American remains in published notices.

If you want to share something else with ProPublica, we’d like to hear from you.

If you have questions about implementing or complying with the Native American Graves Protection and Repatriation Act, get in touch with National NAGPRA or the NAGPRA Community of Practice.

We use the word “tribes” to refer to all groups that institutions made Native American remains available to under NAGPRA. This includes tribes, nations, bands, pueblos, communities, Native Alaskan villages, Native Hawaiian organizations and non-federally recognized groups.
