2. Public health analysis at local level Use of census data to inform Joint Strategic Needs Assessment to provide information on health and care needs of local populations for commissioning services. Main items used Population count Age profile Household composition Type of accommodation, including whether a mobile or temporary structure Ethnicity Health, even though self assessed Support and care given to others with health needs by number of hours

3. Small area statistics Some councils keen on the administrative data approach, which would see more regular population estimates at district level at the expense of population characteristics at the very local level. Public health needs small area statistics Individual data items Index of Multiple Deprivation scores Neighbourhood statistics – include administrative data

5. As hoc analyses using census data Ad hoc queries to Public Health departments informed by Census data.

10. Summary The Census is used locally in Public Health because it provides open, accessible, consistent, standardised data at no additional cost, with no restrictions on availability, all in one place. Valid, robust and measures what it purports to measure Particularly valuable where there may be a lack of alternative local sources of data, such as traveller populations Data available for small areas
