Population churn

Population turnover rates relate the combined inflow and outflow for an area to the resident population. The rates can provide a useful measure of the potential disruption to local services caused by migration into and out of the borough.

Based on the GLA’s analysis of the average 2001–2006 population turnover rates (London Borough Migration 2001-2006 - DMAG briefing 2008-10), churn for Tower Hamlets was 189 per thousand residents, nearly 19 per cent of the population.

This figure combines the inflow rate (94 per 1000 residents) and the outflow rate (95 per 1000 residents). When movement within the borough is included (53 per 1000 residents) churn rises to 241 per thousand residents or just over 24 per cent of the population.

Based on this latter figure, Tower Hamlets ranks eleventh highest amongst the 33 London authorities (including The City of London); Westminster tops the list with 314 per 1000 residents and Havering ranks lowest with 124 per 1000 residents.
