Survey years in column headings represent the midpoint of data collection years for each of the of the two NSFG surveys (2006–2010 and 2013–2015). We report in text characteristics for which method use changed significantly at p<.01.

NA, not available. Due to small cell sizes, we did not test for differences between years.
