Hi,

I am looking at the effect of different variables on the recycling rate in England.
I have 311 local authorities in England over 20 quarters and am running a regression including income, population density and household size. I have data on income and population density by quarter for each local authority.
However I was only able to obtain data for household size by year, and this does not separate by local authority it is an average for all the UK (I only have 5 values for household size).

How can I interpret the coefficient on household size?
