Earned Income Tax Credit Laws

The Earned Income Tax Credit (EITC) is a tax benefit for working people with low to moderate income regulated at the state and federal-level. The credit incentivizes work and reduces poverty for individuals and families by establishing credits that apply to an individual’s tax liability, with any excess potentially awarded as a cash refund. Studies of EITC laws have shown health improvements associated with the credits, most significantly among single mothers and children.

Complete Streets Dataset

Roads in the United States are rarely developed with consideration for users other than motorists. This can result in dangerous conditions for pedestrians, bicyclists and users of public transit. Complete Streets policies seek to create safer roads by designing them to balance the needs and priorities of all users. These users typically include motorists, pedestrians, bicyclists and transit users. Complete Streets are often implemented through state or local transportation policies, state laws and regulations, or city ordinances.

This map identifies and displays key features of state, county, and city-level laws governing the residential eviction process in 40 U.S. cities — the 10 largest cities in the four Census regions — in effect as of August 1, 2018.

Abortion Laws

This dataset provides a general overview of 15 regulatory areas related to abortion in the United States, and includes laws, case law, and attorney general opinions in effect as of August 31, 2020.

Medication-Assisted Treatment with Methadone (MAT) Laws

Medication-Assisted Treatment (MAT) uses medications, such as Methadone, in conjunction with behavioral therapy and counseling to treat opioid addiction. MAT with methadone is required to be distributed to individuals through an Opioid Treatment Program (OTP). MAT with methadone for opioid addiction is subject to federal law, with specific requirements such as physician evaluations, toxicology testing, counseling, and treatment planning. Some states go beyond what is required by the federal law and place stricter restrictions on OTPs, while other states simply defer to the federal law.

Drugged Driving Laws

According to the 2014 National Survey on Drug Use and Health (NSDUH), 10 million people aged 12 or older reported driving under the influence of illicit drugs. As more states have legalized medical and recreational marijuana and with the high prevalence of prescription drug use in the United States, drugged driving has become a public health issue. In response, states have passed laws intended to decrease traffic accidents and deaths related to drugged driving. 

PDMP Reporting and Authorized Use

Prescription drug monitoring programs (PDMPs) collect patient-specific prescription information in centralized databases in an effort to reduce the misuse of controlled medicines. This dataset captures laws governing PDMP reporting and authorized use. The topic includes who is required to report to the PDMP, what drug schedules must be reported to the PDMP, and whether the PDMP is authorized to share data with insurers, state Medicaid programs, or PDMPs located in other states.

This is a longitudinal dataset, displaying laws from January 1, 1998 to July 1, 2016.
