We confirm that even across wards within cities (for instance, across wards in the Borough of Greenwich in London), ‘weak’ socio-economic fundamentals are strong predictors of the Vote Leave share. The same pattern as across local authority areas can thus be observed across wards, even within large cities. The fact that support for Vote Leave may be less visible in a large city like London is merely down to composition effects in that London has relatively strong socio-economic fundamentals on average compared to the rest of the country.
