What We Do

The California Immigrant Data Portal is a project of the University of Southern California’s Equity Research Institute (ERI), formerly known as the Center for the Study of Immigrant Integration (CSII). ERI carries forward CSII's immigrant inclusion work to: promote narratives to support the integration of diverse immigrant and U.S.-born communities; lift up the intersection of racial justice and immigrant rights; and strengthen the base for inter-sectoral collaborations.

Since 2008, the Institute’s immigrant inclusion work brings together three emphases: scholarship that draws on academic theory and rigorous research; data that provides information structured to highlight the process of immigrant inclusion over time; and engagement that seeks to create new dialogues with government, community organizers, business and civic leaders, immigrants, and the voting public.

Learn more about our Immigrant Inclusion and Racial Justice work here.

Our perspective on immigrant inclusion is anchored by three guiding principles:

First, immigrant inclusion is everyone’s business. Over 10.5 million Californians are immigrants, living and working in every county in the state. Honoring their presence in our communities through implementing programs and policies that improve the well-being of immigrants and their families not only improves their lives in real ways but also creates ripple effects, improving neighborhoods, schools, workplaces, and beyond, for both immigrants and U.S.-born residents.

Second, successful immigrant inclusion can only happen when we lift up racial justice and address longstanding inequities. After all, inclusion efforts are often stymied by anti-immigrant sentiment and policy-making which is rooted in racism. Moreover, immigrant inclusion does not mean that immigrants should “hopscotch” over other groups on their way to success but rather work together to address common challenges facing immigrants and Californians of color, including over-incarceration, worker exploitation, discrimination, and a lack of political power. Immigrant inclusion is part of a broader social justice agenda that seeks to create a better future for everyone in our state.

Third, California must lead on immigrant inclusion and seek to provide a model for the rest of the nation. California’s willingness to invest in both those who are here, and the newly arrived, has led the state to become the fifth largest economy in the world. Continuing to build a state that is a welcoming place will not only benefit the next generation of immigrant families, but will grow our economy and build a more stable future for all. Because of this, we must not just resist anti-immigrant policies and attitudes but also lead with big and bold ideas to continually strive to improve the lives of immigrants and others in the Golden State.

California's Native Nations

The land that we now call California is located within the ancestral homelands of over 150 California Native American Tribes.1 Today, California is home to the largest population of Native Americans in the United States. While the state is home to many Indigenous groups, including people from Tribal Nations that were the original inhabitants of what we now call California (map), there are also many Native Americans from other regions of what we now call the United States (representing hundreds of non-Californian Tribes and Native Nations, many of whom were forced into California and Californian urban areas via U.S. policies and actions, such as the Indian Relocation Act), Indigenous immigrants (including Canadian First Nations and Inuit, Mexican, Central and South American Indigenous peoples, and Pacific Islander nations and people), many of whom were also forced into California as a result of U.S. policies and actions abroad.

While this website provides data on immigrant, migrant, and refugee communities, we recognize that California is home to Native Nations on whose land we are living. We want to challenge the uplifting but inaccurate narrative that the state was “built by immigrants.” Instead, we want to acknowledge that the land we reside on was taken by a settler-colonial society that exploited native, immigrant, migrant, and enslaved people – stealing labor, knowledge, and skills – to build what we now call California. Immigrant communities, like U.S.-born Californians, must grapple with what it means to live on stolen land, understand our role and responsibilities as guests on Native American homelands, and be committed to supporting the struggle for Native Nations’ sovereignty and self-determination.

Some resources to learn more about California’s Native Nations:

California Public Resources Code Section 21073. “California Native American tribe” means a Native American tribe located in California that is on the contact list maintained by the Native American Heritage Commission for the purposes of Chapter 905 of the Statutes of 2004.

Our Data

The California Immigrant Data Portal draws data from a variety of federal, state, and local sources to better understand California’s diverse immigrant population, and the context for immigrant inclusion along key measures of economic mobility, warmth of welcome, and civic participation. The portal provides decades of data for counties, sub-county areas, cities, and the state overall that are geographically consistent over time and disaggregated by immigration status, race, and ancestry.
