Definitions and data sources

The first graph focuses on pay differentials.  It shows four statistics:

In each case, the statistics are shown as a proportion of average (median) hourly pay of full-time male employees thus providing a measure of earnings inequalities.  The left-hand axis shows proportions at the 10th percentile and the right hand axis shows the proportion at the 90th percentile.  The restriction to full-time employees only is to avoid the distorting effects of differences in the full-/part-time balance either by gender or over time.

The second graph shows, for the latest year, the distribution of employees across the pay spectrum with the data show separately for part-time women, part-time men, full-time women and full-time men.

The data source for both graphs is the Annual Survey of Hours and Earnings (ASHE).  Some detailed changes were made to the ASHE survey base in 2004 and an adjustment has been made for this in the first graph.  The proportions in the second graph have been calculated from the hourly rates at each decile using interpolation to estimate the consequent proportion earning in each of the pay groups.

Overall adequacy of the indicator: medium.  ASHE is a large annual survey of employers but the published data does not provide direct estimates of the number of people at various low pay thresholds.
