Demographic Structure of Detmold Region

07This work analyses the general demographic structure in Der Regierungsbezirk Detmold(EN: Detmold region). The overall population trend within the region and general amount of population size, population density, growth rate in municipalities were illustrated on maps and bar charts. Maps were created by utilizing QGIS.

Population Trends

Based on the population statistics, we can see the population trend in the entire region from 1962 to 2013. The population trend over this period of 51 years is presented on the line chart (see diagram 1). The chart depicts that there is an upward movement from 1962 to of the mid-1970s.  After 1980s the population remains relatively stable for a decade. After a population growth in the early 1990s, it slightly starts to downturn in 2004.

Statistics show that Bielefeld currently has the largest number of population (324.970) within the region, as the map and bar chart highlight. It is almost twice as big as Paderborn which is the second largest city in the region. The municipality that has the least population (5.076) is Marienmünster, located in Kreis Höxter.

The total number of population was determined as 2.030.645. According to the statistics that are taken from DESTATIS, the total population number in North Rhine-Westphalia is 17.6 million and 80.5 million in entire Germany, in comparison. So we can say that the region´s population is equivalent to 11% of the state North Rhine-Westphalia and 2,5% of the country.

Population Density

detmold-diagram-3“Population Density” is expressed as the number of people per 1 square kilometer. Calculations have been made by dividing the population number in 2013 of municipalities by their area land.

It can be seen on Diagram 3 that Bielefeld, with its population of 324.970 and an area of about 259 km2 dominates other cities: there are 1256 inhabitants per 1 kilometer square.  Herford, Gütersloh, Hiddenhausen, Minden and Paderborn are the upcoming dense municipalities exceeding the rest.

In Detmold Region, the average density was found as 315. According to World Bank statistics, the average density in entire Germany is 236. So, it is not wrong to say that the population density of Detmold Region is more than the average in the whole country. We can observe that the southern east part of the region is relatively less dense than the northwest part. Borgentreich is the least dense municipality with 64 people per 1 km2.

Image 3  and Diagram 4 illustrate the difference of population size between the years 1962 and 2013 at 51 year interval. While the negative percentage numbers indicate a decrease in number of population, positive numbers demonstrate a growth that occurred in years.

The percentage growth rate is calculated simply by dividing the difference between populations in 1962 and 2013 by the population size in 1962 and multiplying with 100.

We can say that there is a general growth within the region. Harsewinkel is noticeable that its population size was doubled in 51 years. However, Herford, Borgentreich and Höexter are the municipalities where the population size did not grow : contrarily they experienced a decrease over the years.
