In ecological inference one uses data which are aggregated by areal units to investigate the behaviour of the individuals comprising those units. Aggregated data are readily available in many fields and within a wide variety of data structures. In the structures considered, the aggregate data are characterized by the absence of available data in the internal cells of a cross-classification. The aim of the ecological methods is to estimate the expected frequencies of such internal cells, which may be conditional on chosen covariates. Four methods of ecological inference are reviewed and their properties and appropriateness considered. These methods are then applied to data for which the internal cells are known and their performances compared.

The changing relationship between class and political party in Britain has been the subject of considerable debate among social scientists, much of it about the measures used to identify patterns of change. The paper updates previous work by extending it to the most recent British election, by comparing different procedures for allocating respondents to classes, and by using a recently developed log-multiplicative (`UNIDIFF') model which is especially appropriate for testing whether or not classes have converged in their voting behaviour. The analysis confirms and strengthens previous interpretations which have argued that the class basis of partisanship is not in continuing decline.

Secondary analysis of General Household Survey and Labour Force Survey data shows how the structure of families in Great Britain has changed over the last 20 years. Dependent children are now less likely to be living in a couple family and more likely to be living with a lone mother who is either single or divorced. Families in simple households with just two generations have become more common over time. Lone mothers are now more likely to be living in simple households. The paper also considers how the number and ages of dependent children are associated with family and household type. Log-linear models are used both to smooth the data and to predict family structure in the year 2000. Gaps in our knowledge about current family structures are discussed together with implications of the findings for social policy.
