The homelessness monitor is a five year study that will provide an independent analysis of the impact on homelessness of recent economic and policy developments in England. The key areas of interest are the homelessness consequences of the post-2007 economic recession and the housing market downturn. The other main thrust of inquiry is the likely impacts of the welfare, housing and other social policy reforms, including cutbacks in public expenditure, being pursued by the Coalition Government elected in 2010. This year 4 report monitors the impact on homelessness of the economic downturn and effects of welfare and housing reform and analyses key trends from the baseline account of homelessness established in 2011 up until 2015, or as close as 2015 as data availability allows. It also highlights emerging trends and forecasts some of the likely changes, identifying the developments likely to have the most significant impacts on homelessness. We will continue to monitor the impact on homelessness of the economic downturn and effects of welfare and housing reform over the year in order to provide a substantive evidence base and will report on them in 2016. While this report focuses on England, parallel Homelessness Monitors are being published for other parts of the UK.
