HIGHLIGHTS·   The majority of IDPs living in collective centres reside in Kyiv (23 per cent), Donetsk (17 per cent), Kharkiv (13 per cent), Odesa (13 per cent) and Dnipropetrovsk (11 per cent) regions, while the remaining 23 per cent IDPs are in the rest the of country.·   Demographics: Women and children constitute over 73 per cent IDPs residing in collective centres, over 13 per cent residents are elderly. There are 15 per cent fewer men in collective centres than in the overall IDP population (REACH 2015), which may be explained by the number of vulnerable female-headed households and families with many children in collective centres.·   The highest occupancy rates are among Kharkiv, Dnipropetrovsk and Zaporizhzhia regions. Overall, there is a trend of declining occupancy rates since mid-2015. Increased occupancy is observed in larger urban centres and their vicinities, while remote rural and semi-urban places, over 50 per cent of places are vacant.·   Duration of stay: Numerous collective centre managers, especially near the line of contact and large urban centres report that IDPs do not stay for long-term, rather come for several nights and use collective centres for short-term shelter.·   Ownership type: The majority of collective centres are privately owned, while only 38 per cent are public or communal. During the past year, many public and communal collective centres closed, while closure rates of private collective centres are significantly lower.·   Closure of collective centres: 52 collective centres out of 271 monitored have closed since the start of the crisis, with 32 collective centres of the 52 closing during 2015-16 alone. In the majority of cases, IDPs left for private accommodation or other collective centres within the same district, while some relocated to other parts of the country or returned to their place of origin. The main reasons for closure were high debts and financial unsustainability, seasonal closure during winter, or IDPs finding other shelter solutions. 11 per cent of summer camps which closed for winter reported possibility of reopening during summer.·   Evictions: 15 collective centres reported risk of eviction (over 700 people); the main reason is debts for utilities and rent. All cases are being followed up with partners.·   Contingency: Public and communal collective centres reported that they are ready to accommodate newly displaced people in case of massive influx upon request from respective authorities.
