A: The best data I know of on this question come from a study by Heaton, Goodman, and Holman that was originally published in 1994 and republished in 2001 looking at the characteristics of Mormon families. Their study analyzes data from the National Survey of Families and Households (NSFH). Newer data from the NSFH is available, but has yet to be analyzed on this question (as far as I know). Here is the data on the variables you asked about:
| Mormon women | non-Mormon women | |
| age | 44.8 | 45.2 |
| race (% white, non-Hispanic) | 94.3 | 79.8 |
| employment (% gainfully employed) | 54.6 | 55.0 |
| mean income | $6,263 | $7,905 |
| mean years of education (12 is a high school degree; any more indicates years of college) | 13.0 | 12.6 |
| number of children | 2.96 | 2.04 |
| ideal number of children | 4.61 | 2.78 |
| % in metropolitan area | 49.7 | 69.8 |
| % in West | 44.8 | 45.2 |
| % currently married | 63.4 | 53.8 |
| % ever divorced | 28.1 | 27.8 |
| mean age at marriage | 21.0 | 21.3 |
| % who have cohabited | 7.9 | 15.7 |
| mean frequency of sexual intercourse (in the last month) | 8.0 | 7.2 |
| mean hours spent in household tasks per week (washing laundry, cooking, etc.) | 57.4 | 44.9 |
