Distribution

How values are spread across the records that have one. Use it to check that the attribute tells records apart: when one value holds nearly everyone, it will not separate audiences much. Each bar is a band of values, lowest on the left. The shading groups the bars into percentile bands.

Share by value

n = 31,079

Share of postcodes with a known value in each band. The middle 50% falls between 3.38 and 11.28 km, shaded darkest.
