Correlation between socio-economic subgroups and mean annual exposure to NO2 in Scania, Sweden (2001). The correlation coefficients for those born in OC (Other Country) and those with a low level of education are not presented since they are the exact inverse of the correlation coefficients for those born in Sweden, and those who are highly educated, respectively. The proportion with:"high level of education and concentration of NO2" is calculated for the age-group 25–64 years. |
