Sexual and reproductive healthcare restrictions imposed by faith-based hospitals prevent women, sexual minorities, and gender minorities from accessing the full range of comprehensive healthcare. The share of faith-based hospitals in California has increased rapidly in recent years, but no analysis has been completed to understand their distribution and rate of growth. In this paper, we calculate the percentage of religiously affiliated acute, short-term hospital beds per California county. We find that faith-based hospitals have a majority market share in 17 out of 58 California counties. Furthermore, while the percentage of faith-based hospitals in these counties has remained relatively stable from 2000-2010, this proportion has increased tenfold in the past decade. Our data suggest that the expansion of faith-based healthcare systems in California presents a significant barrier to sexual and reproductive healthcare access.
