The first collection of maps is now available to view. It is a simple one, the 28 boroughs that formed Inner London before 1965 that are now twelve London boroughs. It is worth noting that even in this period some of the boroughs are the result of earlier amalgamations and at the time many covered more than one recognisable community.
Some were very large in terms of population. Wandsworth, for example, peaked at 353,110. Other boroughs closer to the City of London were very small and experienced rapid depopulation as the suburbs in outer London grew. Shoreditch had a population of 111,390 in 1911, reduced to 40,455 in 1961.
