Educational assortative mating across marriage markets: non-Hispanic whites in the United States
1Ohio State University, USA. lewis@datalib.com
Abstract:
Whether local marriage market conditions shape marriage behavior is a central social demographic question. Most work on this subject, however, focuses on one type of market condition--sex ratios--and on a single outcome--marital timing or sorting. We examine the impact of local marriage markets' educational composition on educational assortative mating and on how sorting varies with age. We estimate a discrete-time competing-risks model of educational sorting outcomes, using individual data from the NLSY and community descriptors aggregated from census microdata. Results show that residents of educationally less favorable marriage markets are more likely to marry down on education, and that (for women) their chance of doing so increases with age more than for residents of more favorable markets.

There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
