How do Jews live in non-Jewish communities?

Jews live in non-Jewish communities the same way that non-Jews live in Jewish communities, in that they own houses, drive cars (on the proper days), send their kids to school, buy food in the supermarket, etc. In places where the Jewish presence is minimal, such as most East Asian countries, Jews who live in those areas have to be willing to compromise on food or other restrictions that are harder to perform without a Jewish community nearby.
