„“No response” values of less than 5% are not shown. Percentages refer to the total population of 4002.

*¹ Census 2011; *² Microcensus (MC) 2014; *³ numbers calculated by us based on the MC;

*⁴ this mean value is based on the 10 possible categories of income, in Euros (<500, 500 to>1000, …, 4000 to >4500, >4499). Due to the last category, the actual mean income is underestimated.

*⁵ Continuous Household Budget surveys (LWR) 2014; *⁶ low = no qualification or Volks- or Hauptschulabschluss (year 9 lower secondary school certificate); medium = polytechnic secondary school (Polytechnische Oberschule; POS), Real- or Mittelschulabschluss (year 10 lower secondary school certificate); high = Abitur, Fachabitur (secondary school certification, allows entrance to a university);

*⁷ numbers refer to number of households, not number of persons per household; *⁸ numbers refer to the population over 18; *⁹ Microcensus 2013
