Then I have a Sensus sub-place vector layer with over 10 000 sub-places which indicate the number of unemployed citizens per polygon. The Sensus sub-place layer therefor overlaps with the police districts and when visualize some sub-places can make up 1% up to 100% of a given police district. Most of the police districts also contains 4 or more sub-places. The problem is I want to calculate the ”approximate” unemployment rate per police district by using the data from the Sensus sub-place layer. Is there perhaps an explanation on how I can determine” approximately proportionally” what the unemployment is per police district. I am new to QGIS and not up to date with programming, however any assistance would be appreciated.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regards<o:p></o:p></p><p class=MsoNormal>Deon Pretorius<o:p></o:p></p></div></body></html>
