In addition to asking about the number of children in their households, the survey also asked respondents how many children they have, whether at home or not. This question includes grown up children who have left home and, hence, has a notably different distribution, as we can see in Figure 1 (above, using weighted data). Whereas almost three quarters of people (73.4%) have no children at home, only two fifths (41.7%) have no children at all. Similarly, more than half of people (52.3%) have one (16.4%), two (26.3%), or three (9.6%) children, whereas only a quarter (24.1%) have between one and three children living at home. Finally, whilst one in seventeen people (6.0%) have four or more children, fewer than one in one hundred and sixty people (0.6%) have that many children living at home. Thus, unsurprisingly, there are lots of people who have children that have grown up and flown the nest, and notably fewer people who have children still living at home with them.
