Choose what to group by, then tick up to 3 rows in the list. Each one becomes a line on the chart. Remove one with the x on its tag, or press Reset to go back to the biggest group.
When two or three audiences are on the chart, each line starts at 100 on the first day shown, so groups of very different size can be compared as growth. Use Show real counts to see the actual numbers.
Counts for each country, language and age group are recorded once a day from Prolific's public figures, and the page refreshes hourly. Country and age together is only tracked for the last 30 days.
