Research Range and you will Analytic Approach

Analysis within statement are from the brand new Guttmacher Institute’s 5th federal questionnaire off abortion people, which used a sampling build, questionnaire and you can fieldwork method like people included in prior iterations used in the 1987, 1994–1995, 2000–2001 and you can 2008. 14–17 Reveal malfunction of one’s studies range measures and you can duplicates of questionnaire tool come in the brand new appendices of that it statement; we provide a brief bottom line less than.

Anywhere between , we accumulated information off 8,380 respondents getting abortions at 87 institution. We utilized a several-web page, self-given questionnaire found in English and Spanish.

Within this report i introduce descriptive statistics on the abortion patients’ group services, and you can evaluate these features having the ones from clients within the 2008.

Loads have been developed to help you be the cause of diligent nonresponse and you will variation regarding the original business sampling package. Destroyed guidance having trick group parameters was imputed making use of the responses regarding respondents with similar qualities. All the analyses was according to weighted data and you can was indeed presented using new svy order when you look at the Stata type thirteen.step 1 to help you take into account the newest state-of-the-art sampling build.

Given that 2011 is one of previous seasons where the total level of abortions in the usa can be obtained, we had been unable to imagine new abortion speed (exactly how many abortions for each and every 1,one hundred thousand females) by the subgroup for this report. Rather, we constructed a keen abortion index (otherwise cousin abortion rate) since a good proxy measure of pricing to assess brand new relative accounts regarding abortion round the subgroups. Per abortion index is the proportion off abortion patients in the a good given subgroup (e.grams., a certain age-group) in accordance with the brand new proportion of the many U.S. people aged 15–49 who are for the reason that same subgroup. If the these types of proportions are identical-expressed because of the a directory of 1.0-the subgroup’s cousin abortion rates is the same as the general federal speed. If your subgroup is overrepresented certainly abortion people (list more than step 1.0), its relative abortion rates is a lot more than mediocre; when it is underrepresented (index lower than step 1.0), its relative rates try below average. Rather, an increase in this new abortion index to own a good subgroup over time cannot always mean an increase in the new subgroup’s abortion rate. Then it the outcome in case the subgroup’s abortion rate diminished at the a reduced rate than simply regarding the population.
