Historical dataset of population level and growth rate for the Cologne, Germany metro area from 1950 to 2025.

The dataset contains information on the total resident population, male and female resident population on the county (Kreis), canton (Bezirk) and national level for the years 1969 to 1989. The information is based on the Statistical Yearbooks of the German Democratic Republic. The numbers for the county and national level are taken directly from the Statistical Yearbooks. The numbers for the canton level are the aggregated numbers of the county resident population (total, male and female) per canton and year. All population figures reflect the situation at the end of each year. Up to and including the year 1981, December 31 is given as a specific date of the recordings.
The research for this dataset was financed by the research grant KO 2239/3-1 “Spontane Revolution oder lange Wende? Eine soziologische Analyse der DDR und ihres Niedergangs auf Basis von Eingabenstatistiken zwischen 1970 und 1989” of the German Research Foundation (Deutsche Forschungsgemeinschaft;DFG).
