In 1898, Borlänge was granted privileges by the national Swedish government as a market town (Swedish: köping) with about 1,300 inhabitants, but still today it belongs to the Church of Sweden's regionally historically dominant parish of Stora Tuna, centered on a large medieval church by that name (meaning great enclosed farmyards), now located in a rural district east of the city.
In the 1990s, Borlänge had the highest crime rate per thousand inhabitants in Sweden, dominated by violence and theft.
This migration had decreased by the following decade, with most newcomers in Borlänge now consisting of asylum immigrants from Syria and Eritrea.
An agreement between the Borlänge Municipality and the Swedish Migration Board to receive 30 refugees per year has contributed to the population growth, with many arriving via family reunification.
Over a five-year period, the number of inhabitants in Tjärna Ängar increased considerably, as 1,000 young persons relocated to the neighborhood.
[8] In its December 2015 report, the Swedish Police Authority placed the Borlänge's Tjärna Ängar district in the second highest category of urban areas with high crime rates.
[10] In the summer of 2016, there was widespread vandalism, cars were torched and when firefighters arrived, they were attacked with stones and had to wait for police to escort them in order to complete their mission.
Although the official number of inhabitants are 3500, unofficially the population may be as high as 6000-10000, when water usage and the weight of generated household waste is analysed.
The city boasts a successful football team IK Brage, named after the Norse god, has a history of 18 seasons in the Swedish Premier Division (Allsvenskan).
Brage plays in green and white and hosts its home games at Domnarvsvallen Stadium in Borlänge, with a seating capacity of 6,500.
