Background: Abortion is a common medical procedure, yet its availability has become more limited across the United States (US) over the past decade. Although women may not always know where to go for abortion care, they often use the internet to find reproductive health information and there appear to be more online searches for abortion in states with more restrictive abortion laws. While previous studies have examined the distances women must travel to reach an abortion provider, to our knowledge no studies have used systematic online searches to document the current geographic locations and services of abortion facilities.Objective: To describe abortion facilities and services available in the United States from the perspective of a potential patient searching online and to identify U.S. cities where people must travel the farthest to obtain abortion care.Methods: In early 2017, we conducted a systematic online search for abortion facilities in every state and the largest cities in each state. We recorded facility locations, types of abortion services available, and facility gestational limits and summarized the frequencies by region and state. If the online information was incomplete or unclear, we called the facility using a mystery shopper methodology, which simulates the perspective of patients calling for services. We also calculated distance to the closest abortion facility from all U.S. cities with populations ≥50,000.Results: 780 facilities were identified through our online search, with the fewest in the Midwest and South. Over 30% of all facilities advertised the provision of medication abortion services only; this proportion was close to 40% in the Northeast and West. The lowest gestational limit at which services were provided was 12 weeks in Wyoming; the highest was 28 weeks in New Mexico. People in 27 U.S. cities must travel over 100 miles to reach an abortion facility; the largest number of such cities is in Texas which has 10.Conclusions: Online searches can provide detailed information about the location of abortion facilities and the types of services they provide. However, these facilities are not evenly distributed geographically and many large U.S. cities do not have an abortion facility. Long distances can push women to seek abortion in later gestations when care is even more limited.
