This statistical briefing note compares differences between Great Britain and Northern Ireland in items reported as ‘necessary’ using the harmonised UK Omnibus dataset. Heat maps and relative risk ratio calculations were carried out separately for all adult and child items and activities. No major differences are apparent between respondents.

The statistical briefing examines the implications of a programming error that resulted in higher than expected amounts of missing data in the ‘sort card’ sample of the June 2012 Northern Ireland Omnibus Necessities Module. It concludes that the missing data can be considered to be MAR (Missing At Random) and they are ignorable for analyses of the proportion of respondents considering an item or activity to be a necessity as long as both the missing data and the don’t knows are excluded from the numerator and denominator i.e. if the don’t knows are set to ‘missing’.

This conceptual note explores work, paid and unpaid, looks at how the PSE research can examine the impact of the trend to an economy based on higher levels of low pay and insecurity and the impact of this on the extent to which paid work reduces poverty. The PSE also explores the quality of work in terms of aspects such as job security, control, flexibility, physical and social environment, anti-social hours and overall satisfaction. And finally the PSE study explores unpaid work and captures estimates of time spend on various forms of unpaid work covering work in the house, caring and voluntary work.

How can we tell whether any differences between different groups, such as men and women, in their attitudes to necessities is down to chance or not? This statistical note explains why the PSE team uses 'relative risk' rather than 'hypothesis testing'.
