Analysis, Products, and you may Actions

Given that revealed into the Desk step one, i fool around with research regarding about three studies so you can perform the analyses: brand new 19682015 February Newest People Surveys (CPS); the fresh 1960, 1970, and 1980 U.S. ); in addition to 19842014 Questionnaire of cash and you will System Contribution (SIPP) (You.S. Census Bureau 2015). The fresh new CPS was the priining fashion within the economic homogamy prior to and you will after parenthood. It is a cross-sectional family questionnaire that has been generally accustomed data alter when you look at the inequality in america. It is perfect to the investigation as it possess large products, boasts money details about one another couples, and that’s consistent all over a lengthy time span.

Much of the CPS analyses believe in an example of partnered partners where the spouse is actually decades forty five otherwise more youthful and you can their eldest youngster try decades 010 (N = 333,455 people).

The newest CPS studies do not allow us to identify the fresh timing out-of income relative to parenthood for couples heading then straight back than 12 months ahead of very first birth. One good way to grow new pre-beginning homogamy level which have CPS research, but not, is to become all married childless couples (understand the history line in Table step 1).

I restriction the main sample in order to young mothers to attenuate the fresh inclusion from repartnered people, attrition due to separation, and elderly lovers with youngsters out from the house for example maybe not claimed to your CPS roster.
