Measures of reported disability prevalence are often subject to great variability and this can make drawing precise conclusions from them difficult. In this box, we considered two examples where measures varied. The first related to differences between Labour Force Survey and General Health Survey measures of working-age disability prevalence and the second to large changes in the former. We discussed differences in methodology and changes in attitudes as possible drivers.
Public financial support for disabled people extends beyond the extra-costs disability benefits and includes several other welfare payments. This box gave an overview of some of the most important interactions between disability and other benefits that provide support for disabled people.
Our ability to forecast accurately is heavily dependent on the quality of the data we can use. In this box we explained how statistical and expenditure data could be distorted by problems in delivery of the benefit, and the difficulties this creates in identifying emerging trends in the data.
There are several possible approaches to forecasting benefit spending. In this box we outlined the key issues the modelling of disability benefits needed to address, the three approaches we used to forecast spending, and the strengths and limitations of each, concluding that a combination of approaches was better than reliance on any single one.
