This document summarizes a study estimating the number of homeless people sleeping rough in 4 cities in the Netherlands. Researchers used shelter registration data and interviews with homeless individuals in shelters during winter periods to estimate ratios of shelter usage to rough sleeping. Applying these ratios to total shelter admissions, they estimate that on average, 250 people were sleeping rough across the 4 cities, with rough sleeping rates varying between cities from 5.8 to 22.9 per 100,000 population. Only a minority (12-36%) of rough sleepers were considered citizens of the cities studied.

During periods of frost in wintertime….
Shelters are free of charge and accessible for all
homeless.
Homeless ‘sleeping rough’ are actively motivated to use
a shelter.
Shelter capacity is adapted to demand.

Conclusion / limitations
Simple indicator of the number of homeless sleeping rough for
comparison of urban areas.
Limitation: estimated number on an ‘average’ night.
Does the ratio of the nights spend in shelter / sleeping rough,
reflects the true ratio….???
Both shelter + sleeping rough ≈ 43 /100,000 population
Sleeping rough varies ≈ 6 – 23 / 100,000 population
Only a minority of those ‘sleeping rough’ is considered as citizen of
the city’s region.
