3. “UK is accused of failing children” Headline BBC news 14/2/07 – UK comes bottom of league table for child well-being across 21 industrialised countries Find the report online: “Child Poverty in Perspective: An Overview of Child Well-Being in Rich Countries”, UNICEF Innocenti Research Centre, Report Card 7 http://www.unicef-icdc.org/

4. Child Well-Being Table 1.Netherlands 2.Sweden 3.Denmark 4.Finland 5.Spain 6.Switzerland 7.Norway 8.Italy 9.Republic of Ireland 10.Belgium 11.Germany 12.Canada 13.Greece 14.Poland 15.Czech Republic 16.France 17.Portugal 18.Austria 19.Hungary 20.United States 21.United Kingdom

5. Measurement and Policy (adapted from Innocenti report card 7:3) ‘to improve something, first measure it’ ‘measurement serves as the handrail of policy’ ‘measurement and comparison shows what is achievable in practice’ ‘comparisons demonstrate that given levels of child well-being are not inevitable but policy-susceptible’

6. How to Use the Index As a stand alone piece of research As a macro level indicator in cross- national multivariate analysis

10. Components of the Dimensions The dimension scores are derived from information on the components Each component draws on one or more indicators The component scores are averaged to arrive at each country’s overall rating

11. Choice of Indicators For each indicator, countries are given a score which reveals how far that country stands above or below the OECD average Where more than one indicator has been used, scores are averaged giving an equal weighting to each indicator Evaluating indicators: reliability and validity

12. Building Indices Indices are composite measures of a concept What to do with the different elements of the index –Add them –Average ranking –Product scores –Factor scores from factor analysis

13. Standardising Variables Creating a common scale to facilitate comparison A z-score is a unit’s score expressed as the number of standard deviation units that it lies from the mean of the variable the z-score tells us two things for each unit/country –how far that individual unit’s score is from the mean –the individual unit’s position in the group

14. Complicating Issues Interpretation of index score Equivalence of items Missing data

16. The Ladder of Abstraction I.Index of the concept of child well-being II.Dimensions of variation within this concept III.Components of each dimension IV.Indicator measures taken from survey data for each component

17. Survey Data Systematic measurement across cases to permit comparison Cases are collected as units of analysis: individual, firm, country The logic of survey analysis is that variation in one variable is matched with variations in other variables (following J. S. Mill A System of Logic)

19. Cross-National Harmonisation of Variables No international standard for measuring complex concepts like income, education, or employment. “Researchers interested in doing cross-national work must investigate the institutions, laws and cultural patterns of a country in order to ensure that the variables they create for their analyses are equivalently defined across countries.” CNEF 2000

24. Design An Index! Put together a short presentation about an index you might like to develop. Consider the points below. (Groups of 3: 15 minute presentation) 1.Identify the concept you want to measure in an index (e.g. child well-being, father-friendliness of policy, support for women’s employment, any other topic of interest to you) 2.Develop a nominal definition of this concept 3.Identify relevant dimensions of the concept (not more than 4 for today’s exercise) 4.Specify appropriate indicators for each dimension (operational definitions). Reflect upon the validity and reliability of the indicators. 5.Which data sets might you use? 6.How would you construct your index?
