Demographic - Who lives where in Budapest?

Hi. I have found sites that describe the various districts and their attractions but I am interested in finding out what social groups live in the various areas. Students and young singles, young professionals, couples with families, retired, poor, wealthy, aspirational.

In the UK there are .gov pages that give the demographic breakdown of a city but I cannot find such a thing for Budapest.

If anyone can help I would be very grateful.
