Data source(s) used: Survey on social actions and services of single and associated municipalites: The survey collects annually information on social services managed by municipalities, so ensuring the monitoring of resources used and generated assets as part of the Integrated Network of local Social Services. The detection of the data is conduct in cooperation with the Ministry of Economy and Finance (MEF), with different Regions and the autonomous provinces of Bolzano and Trento. Data are collected from 2003 through a computing platform accessible to all municipalities and associations involved in the management of the social services. From 2009 it was developed an additional module of the survey questionnaire, called "Questionnaire Day Nursery", to collect more detailed information on socio-educational services for early childhood than those available on all other social services.Warning on municipal dataIn Italy the management of social services is often held up by associative bodies for neighboring municipalities. Thus the disaggregation of data at the municipal level has required the introduction of an estimation component: the number of users, costs and the contribution paid by users includes both the activity of each municipality, both the additional shares arising from associative management of services. The data collected from associative bodies are distributed among the municipalities that belong to it in proportion to the reference population of the services.It should also be noted that there are other forms of association, less structured, which are not represented by the data at the municipal level. For example, through an agreement, a municipality that doesn’t have a day nursery may offer its residents the reception in a structure of a neighboring municipality. In this case, the data are contained entirely in the questionnaire of the owner of the service.
