Adjusted change in preterm birth risk per 1,000 births, with 95% confidence intervals, among non-Hispanic black women associated with absolute increase from 10% to 20% Hispanic density, Asian density, and non-Hispanic black density

	MODEL
ETHNIC DENSITY EXPOSURE	Adjusted: US-born		Adjusted: Foreign-born
	RD ^a	(95% CI)	RD ^a	(95% CI)
Hispanic	−0.4	(−2.1, 1.2)	−3.6	(−5.5, −1.7)
Asian	−1.6	(−5.7, 2.5)	0.1	(−3.8, 4.0)
Non-Hispanic black	2.8	(0.4, 5.2)	1.2	(−1.1, 3.6)

Adjusted differences were calculated for women aged 20-34 who were high-school educated, had 2-5 previous live births, were nonsmokers, were on Medicaid, and resided in a more stable, poorer, and whiter neighborhood.
