• Detailed spatial segregation research on same-sex couples

(ssc) for Germany almost non-existent

• Aiming to figure out about spatial distribution, also over

time

• Questions to answer (among others):

– Which areas (Federal States) are popular, which are not? – Are there differences between male and female ssc? – Do differences in regional distribution over time exist? – Which characteristics of a spatial unit determine the decision of a ssc to live there?

• Scientific Use Files (70%) of German Micro Censuses (1% of

German population) 1996 - 2011, Age 16+

• Unit of analyzes: individuals living in a same-sex couple (ssc)
• Household principle  only couples living together (at main

residence)

• Detection ssc indirectly

Issues

• Data are generally scarce, fluctuation of quantity of ssc

within a geographical unit between consecutive years

• Ssc are underestimated, e.g., due to Item-Nonresponse

(Lengerer & Stein, 2016, DGD-conference Leipzig, Germany)

• Geographical data in Micro Censuses are scarce, only detail

up to Federal State level (n=16)

• Even though with more geographical detail (from Statistical

State Offices, NUTS-2) analyzes difficult as many regional units won‘t have many/ any cases

• How to deal with lack of data? How to improve/ adjust?
