„“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.
