What they're saying: "Data can be used to hold leaders accountable," said Giridhar Mallya, a senior policy officer at RWJF.

• "We have 435 folks in the house that are making decisions or debating decisions everyday about how to use policy to improve the lives of people in our communities, but rarely can they say: 'What does this challenge look like in my district?'" Mallya said.

For example, the dashboard breaks down how residents in districts in the 11 states that have not expanded Medicaid are twice as likely to be uninsured compared to those in expansion states.

• Residents of congressional districts in Arkansas, Louisiana, Oklahoma, and Texas on average are more than three times as likely to be uninsured than those in congressional districts in New England, officials said.
