Taking a Stock of What is Out There

Plan
• International publications on poverty monitoring
• Poverty monitoring: separate activity or integral part of statistical work?
• Data quality: is there a difference between what is needed for poverty monitoring and other purposes of statistical work
3
Sources
• World Bank
• UN Statistical Commission
• UNDP
• Eurostat/European Commission

Key elements of poverty monitoring
• Key poverty indicator: headcount (and associated measures) is monitored over time – There is (are) regular representative survey (s) done with certain
intervals (frequency)– Which allows comparisons over time and with other sources of
data – e.g. SNA (consistency)– And in addition to income/consumption poverty contains other
policy relevant data– That this is transparent process to derive poverty indicators
(access)– There is officially established consistent poverty line which
allows comparisons (regularized)• Key elements of poverty monitoring are identical to
key elements of good Household survey system
5
Does it have to be official?
• Most poverty indicators in the world are based on surveys conducted by the Government statistical agencies
• But a lot of data are supplied by surveys conducted outside statistical offices (often with state support)
• What matters is quality of data and transparency of their use
6
General aspects of quality
• Representativeness: surveys are nationally representative and, for larger countries, regionally/sub-nationally representative.
• Integrativeness: data on different dimensions of living standards are available from the same survey so as to permit a multidimensional analysis.
• Regularity: surveys follow a regular, predictable, preferably annual cycle
• Consistency: surveys are comparable over time and with other data
• Accessibility: unit record data are publicly available according to a transparent, rules-based system.
7
Representativeness, frequencyand cost
• Representative data requires proper sampling
• Larger surveys allow collect representative data for more units / breakdowns
• But larger surveys are more difficult/expensive to do frequently
• It is hard to get an optimal balance
• But it has to be a balance

Consistency
• Comparability over time
• Comparability with other sources of information
• Copnmparabiliity with other countries
11
• Global relationship between survey and NA means holds for ECA; quality problems may be on both sides
• Data show a consistent relationship between macro and survey data at the country level

Consumption Survey/NA for ECA

• On average growth rates as measured by survey data in ECA (and globally) are robust to the measurement problems
• Tight correlation between changes in household consumption from SNA and survey mean consumption (0.75)• But outliers

Coverage/integrativeness
• Covering different dimensions of living standards at once
• Covering mobility at the individual level
• Compatible with other sources of information – Personal ID– GSD– Info on HH networks

Background
• Recent history of poverty monitoring• Systematic data collection effort for poverty
monitoring initiated within the last few years, with technical and financial support from the donor community:– Albania (2002), Bosnia and Herzegovina (2001),
Kosovo (2000), FYR Macedonia (1997), Montenegro (2002), Serbia (2002)
• The first Poverty Assessments produced subsequently
20
Institutional Arrangements
• Data collection and poverty monitoring typically led by the main Statistical Agency, with strong donor support
• Main actors in the donor community: the World Bank, Italy’s Istituto Nazionale di Statistica (ISTAT), and the UK Department for International Development (DfiD) in two or more countries in the Western Balkans; Statistics Sweden/SIDA in Kosovo and UNDP in Bosnia
• Generally very little capacity for poverty monitoring and analysis outside of Government

Pending Issues in Poverty Monitoring
• Sustainability: Generally no provision for the sustained financing of poverty monitoring from central budgetary resources
• Access: Access to primary data remains limited in selected countries, constraining evidence-based policymaking and analytical capacity building.
• Comparability: The shift from one data source to another (e.g., LSMS to HBS) may hinder the creation of a consistent series of poverty monitoring indicators
• Adequacy: HBS, as originally implemented, may not provide sufficient information on broader dimensions of poverty
