how big a problem is homelessness in the uk and what are its causes?

You are asked to write an economic report on the level of homelessness in the UK and on what seems to be its determinants. it is a group project so you should work on my part and try to really use the documents and graphs. I need 500 words on the topic and around 60 words should be a description of my individual contribution to the group project ( my powerpoint slides ). The data you should use is the following : https://www.gov.uk/government/statistical-data-sets/live-tables-on-homelessness#statutory-homelessness-live-tables  AND
