I am watching Brian Boutwell’s (Twitter, RG) talk at a recent conference and this got me thinking. What are we measuring? As far as I know, there are typically two outcome variables used in criminological studies: Official records convictions. Self-reported criminal or anti-social behavior. But exactly what trait are we trying to measure? It seems […]

In a recent paper, Beaver et al looked at the relationships between crime, gender and sexual orientation: This study examined the association between sexual orientation and nonviolent and violent delinquency across the life course. We analyzed self-reported nonviolent and violent delinquency in a sample of heterosexual males (N=5220–7023) and females (N=5984–7875), bisexuals (N=34–73),gay males (N=145–189), […]

Just a quick analysis. When I read the Dutch crime report that forms the basis of this paper, I noticed one table that had crime rates by the proportion of immigrants in the neighborhood. Generally, one would expect r (immigrant% x S) to be negative and since r (S x crime) is negative, one would […]

Emil O. W. Kirkegaard Bo Tranberg Abstract We present and analyze data from a dataset of 2358 Danish first names and socioeconomic outcomes not previously made available to the public (Navnehjulet, the Name Wheel). We visualize the data and show that there is a general socioeconomic factor with indicator loadings in the expected directions (positive: […]

openpsych.net/ODP/2014/04/criminality-among-norwegian-immigrant-populations/ Abstract A previous study found that criminality among immigrant groups in Denmark was highly predictable by their countries of origin’s prevalence of Muslims, IQ, GDP and height. This study replicates the study for Norway with similar results. Keywords: Crime, national IQ, group differences, country of origin — Download paper. Forum thread and supplementary material.

Abstract Criminality rates and fertility vary wildly among Danish immigrant populations by their country of origin. Correlational and regression analyses show that these are very predictable (R’s about .85 and .5) at the group level with national IQ, Islam belief, GDP and height as predictors.
