Abstract [sv]

År 1994 lanserades SAMS-indelningen som alltsedan dess har använts i svenska studier av grannskapseffekter. Här visas att dessa områden inte är så homogena som det ibland förutsätts eller som de skulle kunna vara och att indelningen ser olika ut i olika kommuner. Förklaringar till den bristande homogeniteten söks i städers morfologi och indelningens tillkomsthistoria.

How well do SAMS work in studies of neighbourhood effects?


The subdivision of Sweden into small areas (SAMS) was launched in 1994 and is presented by Statistics Sweden as bringing about in homogenous residential areas. It has been widely used for research purposes ever since. One of the most common fields of research to use SAMS is research on neighborhood effects. The purpose of this study is to estimate how homogenous the SAMS-areas really are. Therefore, each and every SAMS-area has been classified according to its most common type of housing, where after their degree of homogeneity has been calculated as standardized entropy. On average, the areas do not turn out to appear as very homogenous. A reference subdivision is defined by setting out from each and every populated 100m-grid square and its neighboring squares. By comparing the SAMS-areas with this reference, it can be made clear that a heterogeneous realty might explain the low level of homogeneity of SAMS-areas in city-centres, whereas in outer parts of cities and outside them, the low homogeneity of the SAMS-areas is rather a consequence of an insufficient subdivision. This is also obvious from overlaying the SAMS-borders onto satellite images. However, there are huge regional variations which can be explained by the construction of the subdivision. The results of this study points at a need and possibilities to construct a new nationwide subdivision of Sweden into small homogenous areas. Conclusions based on the SAMS-subdivision concerning issues such as neighborhood effects need to be drawn with caution.
