Alarmed states work to avoid vast undercount in 2020 census

Many states are spending millions to make sure their residents fill out next year's census form.

One main reason is that activists and others fear that a question about citizenship that the Trump administration wants to add to the form could scare off Hispanics and other immigrants.

At stake are billions of dollars in federal money for health care, education and other services, as well as a state's representation in Congress.

Perhaps no state has more at risk than California, where no racial or ethnic group constitutes a majority and Hispanics outnumber whites.

California has budgeted about $100 million for education and media campaigns, a figure expected to rise to about $150 million.
