I don’t need help visualising anything, thanks. I work with statistics, so just making the point that some times examples are used to help people visualise what percentages mean, though 50% is pretty obvious. The language used seems to be an effort to humanise numbers, make it mean something personal to you...your mother, your grandmother. It would be a bit daft if they said half of mothers, grandmothers, childless women, sisters, aunts, nieces, trans men, female shop workers, female fork lift truck drivers, Jane who works at the library....The article does say “all” women, so doesn’t need to list them all.
