Abstract
The maps aim to sum up the development and spatial differentiation of registered crime on the district level and they focus on three periods: 1960s (1965-1968), 1990s (1994-1997), and the present (2010-2013). The maps use a typology based on a combination of the crime index (the number of crimes in relation to the number of inhabitants) and the detection of crime (the proportion of crimes with known offender).
The sources of data are figures from the Police Presidium of the Czech Republic (Statistical Recording System of Crime) covering the period from 1994 up to the present. Unique data from the Criminal Yearbooks of the "public constabulary" from the 1960s are also used.
To facilitate comparison, maps are based on the level of administrative districts. The maps also give information on offenders in the 1920s and in the present.
