The demography of Germany is monitored by the Statistisches Bundesamt (Federal Statistical Office of Germany). According to the first census since German reunification, Germanys population was 82,790,700 (31 September 2017), making it the sixteenth-most populous country in the world and the most populous in the European Union. The total fertility rate was rated at 1.59 in 2016 (the highest value since 1972) and in 2011, was even estimated at 1.6 after accounting for the fact that older women contribute more to the number of births than in previous statistic models, and total fertility rates increased in younger generations. In 2008, fertility was related to educational achievement (women with lower levels of education were having more children than women who had completed higher education). In 2011, this was no longer true for Eastern Germany where higher educated women now had a somewhat higher fertility rate compared to the rest of the population. Persons who said they had no religion tend to have fewer children than those who identify as Christians, and studies also found that amongst Christians; the more conservative ones had more children compared to the more liberal ones. In vitro fertilisation (IVF) is legal in Germany, with an age limit set at forty years. As of 2006, 55.7% of Germans age 18 and over were married. According to the 2008-2010 German Community Survey 3-Year Estimates, 51.5% of males and 47.7% of females over the age of 15 were married. The separation rate was 6 per 10 marriages.
