Revisions with no 2050 or 2100 value for Australia are not listed. UN revisions from 2010 to 2019 publish fertility as five-year period averages (e.g. 2045–2050), with no single-year value; their paths are in the chart above. Wittgenstein Centre values are five-year period averages shown at the period's first year (2050 = 2050–2055).
