Standard Poverty Indicators
Limits of the standard approach
1. Dicothomy poor/not poor is an oversemplification of reality.
Poverty is not an attribute but a problem of graduation.
2. Income is not the only indicator of Living Conditions.
a) Income is not a reliable variable, especially in Italy;
1. Poverty is a multidimensional phenomenon to be analyzed
through several indicators (also not monetary)
of living conditions

Income Cumulative Distribution Function
Cumulative distribution function of Income is more informative than HCR

2. significant estimates of Laeken indicators at

Administrative data files

Periodical and low costs estimates at NUTS 3 – LAU 1-2 level but affected by self-selection bias
Many unanswered questions
• Is it possible to formulate new indicators of poverty which extend the traditional indicators (Laeken Indicators) to additional monetary and non monetary aspects and have a longitudinal perspective (measurement of changes in poverty)?
• Is it possible to improve the accuracy of the EU-SILC estimates of traditional and new indicators at NUTS 3 – LAU 1-2 level?
• Is it possible data integration between EU-SILC and Administrative data files? Is it possible to measure and correct the Administrative data files self-selection bias?
In other words:
• Is it possible to satisfy the LOCAL GOVERNMENT AGENCIES INFORMATION NEED?
DASHBOARD OF POVERTY INDICATORS AT NUTS3 – LAU1-2 LEVEL
…it is a good CHALLENGE
The answers are “yes”!!
The solutions requires cooperation between statistical methodologists,
official statisticians and NGAs officers.
Integration of skills…
• …the solutions requires small area estimation methodology
• …also statistical matching methodology
• … and ability to implement software procedures for the estimation
• …a good knowledge of admnistrative data on poverty and deprivation
• …EU-SILC oversampling at NUTS 3, LAU 1-2 level
• …availability of sensible information at NUTS 3 and LAU 1-2 level
• …a clear definition of the indicators to include in the DASHBOARD
• …ability to communicate the solutions to methodologists, official
statisticians, NGAs officers

Aim of the project
The aim of the SAMPLE project is
1) to identify and develop new indicators and models that will help the
understanding of inequality and poverty with special attention to
social exclusion and deprivation.
2) to develop models and implement procedures for estimating these
indicators and their corresponding accuracy measures at the level of
small area (NUTS 3 and LAU 1-2 level).
DASHBOARD OF RELIABLE POVERTY INDICATORS
These goals will be achieved…
…by combining data from national surveys (EU-SILC survey) with
data from local administrative databases. In particular, Local
Government Agencies (LGAs) often have rich administrative data,
which can be used for monitoring actions aiming at tackling
situations of social exclusion, vulnerability and deprivation. Such
data include information on claimants of unemployment benefit and
benefits from other social security programs with the involvement of
stakeholders and Non-Governmental Organizations (NGOs)
representing people experiencing poverty and which act to prevent
poverty.
Aim of the project
Structure of the project
The project is structured in six parts corresponding to six main areas of research or development.
Each part consists of a group of tasks (called Work Package – WP) and will be carried out by a set of participant entities:
WP1-WP4: substantive part of the project, WP5, WP6: management and dissemination
Data sources:Italian, Spanish, Polish, English administrative data and EU-SILC data Sub-contract with Italian National Statistical Institute (ISTAT)
for EU-SILC wave 2008 over-sampling al LAU 1 level (Pisa province)
Structure of the project
The usual indicators of poverty (head count ratio, average income per capita, Gini coefficient) will be completed by the definition of fuzzy monetary and supplementary indicators.EU-SILC will be the initial main source of data.
Estimation of the cumulative distribution function of the variable of interest combining mixed and M-quantile models. Development of small area estimates of usual and new poverty indicators taking into accout the spatial and temporal correlation.
WP 1: New indicators and models for inequality and poverty with attention
to social exclusion, vulnerability and deprivation
WP 2: Small area estimation of poverty and inequality indicators
Structure of the project
WP 3: Integration of EU-SILC data with administrative data
Indicators of poverty and deprivation based only on administrative files are referred only to people eligible for obtaining a service (i.e. medicare, pensions, enrollment in social programs). Therefore, the production of periodical and low cost estimates based on administrative data requires adjustment based also on final EU-SILC estimates.
WP 4: Standardisation and application development –
Software for living conditions estimates
The software is a standalone application whose purpose is to give unskilled users
(i.e. policy makers, social workers from public and private sector) a simple, easy-to-use assessment and reporting tool for main wealth and poverty indicators at LAU 1 and LAU 2 level (R code - free).
Structure of the project
EU-SILC over-sampling
The 2007 final sample size is 150 interviews in the province of Pisa The 2008 final sample size will be 800 interviews distributed by LAU 2 (20
additional Municipalities) proportionate to population size.
• Data collection period: autumn 2008.
• Data production process: managed and carried out by Istat that will provide final validated micro-data referred to LAU 1 LAU 2 level to the Consortium. The release will be in line with the EU regulation on disclosure and access to individual data.
• Nonresponse procedures: defined by Istat according to the standard procedures of the EU-SILC survey protocol (selection of a larger sample, several attempts to abtain answers, weighting adjustment to correct nonresponse bias).
Structure of the project
EU-SILC over-sampling:
Final objectives1. the construction of poverty and inequality measures at local level from several waves
(called pooled estimates) and the comparison between different EUSILC waves results with focus on the local longitudinal changes
2. the definition of effective indicators for the local government at LAU 2 oraggregations of the LAU 2 level.
Intermediate objectives • Understanding the components of the self-selection bias of the administrative data
files on poverty and deprivation1. Testing the accuracy of the poverty and deprivation indicators for the Province of Pisa2. Validating the estimation procedures of the MSE of the poverty and deprivation
indicators at small area level
Project perspectivesProject perspectives
Envisioning the future
1) Social political perspective:
better understanding of inequality and poverty with special attention
to social exclusion and deprivation through local level indicators.
2) Methodological perspective:
producing more reliable (accuracy measured) indicators at the level
of small area (NUTS 3 and LAU 1-2 level).
3) Dissemination perspective:
several kind of actors: statisticians, local and european policy
makers, social researchers, official statisticians, NGOs, citizens
Envisioning the future

2009: Elche (SAE 2009)
2010: place to be defined
2011: Pisa final meeting
