Analytical Method
To compare new market properties from abortion customers into the 2014 that have those in 2008, we basic retabulated the brand new payment distributions out-of abortion people inside 2008 immediately after excluding the brand new 399 individuals who had acquired abortions during the a beneficial hospital function (4% of your take to). I upcoming made use of bivariate logistic regression study to test for significant variations in the latest size of abortion patient subgroups between the two studies. The analyses was indeed considering weighted studies and was basically held playing with the newest svy command from inside the Stata type 13.step 1 so you’re able to account fully for the fresh new cutting-edge testing type of the new survey. While the talked about in the Tips part of the main report, abortion indicator was created given that proxies having abortion rates all over subgroups.
The people advice for some characteristics reported within the Desk step one become from your very own tabulations of your 2008 and 2014 American Community Questionnaire (ACS). They’re decades, race and you can ethnicity, nativity, educational attainment (for clients aged 20 otherwise elderly) and you will friends money. (There are no similar populace data accessible to help us have a look at sexual direction.) Reliance upon these data provide try a range from the prior declaration, where we made use of the brand new 2008 Latest People Survey having most of the market qualities except religion; toward latter, we used the 2006 and you may 2008 Standard Public Survey and you may studies was simply for abortion patients aged 18 otherwise old, as this survey is bound to help you adults.
I transitioned towards the brand new study sources for a few grounds. The newest ACS ‘s the premier house survey in the united states (aside from the census) and offers a lot more direct quotes out-of inhabitants characteristics. 47 To help make the society research comparable over the years, we changed the fresh new 2008 populace data (getting age, race and you may ethnicity, nativity, educational attainment and you may family unit members earnings) utilizing the 2008 ACS.
Brand new 2006–2008 NSFG 
was not obtainable in for you personally to be taken to have prior to analyses playing with analysis about 2008 Abortion Diligent Survey, however, we did put it to use so you can posting dating standing quotes having 2008; we utilized the 2011–2013 NSFG to imagine cohabitation having review with abortion patients into the 2014
In past times i used the current Society Questionnaire Virility Supplement for the amount of past births, however, this information is perhaps not compiled about ACS. Therefore, we utilized the 2006–2010 and 2011–2013 NSFG tools to produce this type of estimates to have review with the 2008 and you may 2014 Abortion Patient Surveys, respectively.
Given that i analyzed marital and you may cohabiting reputation in the course of conception-any where from around three weeks to many days in past times, based on how of numerous weeks’ pregnant the brand new respondent are-there had been zero population-built surveys that have a precisely similar level. New ACS captures simply single or cohabiting people of people answering the actual questionnaire, and thus, such as, cohabiting couples managing a father wouldn’t be seized. The latest NSFG grabs the newest relationship and cohabiting reputation of all of the participants, thus they signifies probably the most similar questionnaire.
Even as we made use of the general Social Survey determine spiritual association one of every woman old 18 or older on the early in the day survey, item wording for the both 2008 and you may 2014 Abortion Patient Surveys is adjusted from the NSFG surveys and you will, for this reason, i modified new 2008 populace guess utilizing the 2006–2010 NSFG, which was unavailable in the event the 2008 Abortion Patient Survey are getting examined. The 2011–2013 NSFG was used to estimate religious affiliation for females just who was in fact out of reproductive years for the 2014.
From these alter, some of the 2008 population rates and you may, subsequently, abortion indices can be a bit unlike in earlier times typed rates.‡‡
