Yep, 1.7a reads as: with £20k/y, you are at the median of all employees
(take any other employee and there is 50% chance his+her salary is more
than your, and 50% it is less than your)

If you restrict to male for selecting the concurrent, it change to 33%
for less and 66% (approx) for more. (£20k is after 30 percentile, but
before 40th)

If you restrict to female, it change to 63% / 36%.

If you select only full time job, all gender, it is back to 33% / 66%.

For a part-time job, it is very near the top (only 15% would earn more).

For a male full time, you are at 25% / 75% )

For a female full time, it's low average (45% / 55%)

Male part time: unrealistic (data for 90th percentile have a coefficient
variation above 5%), yet possible

Female part time: top 10%


Remember that the sampling is biased, culturally:
 * many female with pay & child would opt for part time, far less male
would make the same choice (in the patriarchal society, the male is
assumed to provide the main incoming, so the social pressure on going
part-time with child is gender-biased)
 * on the same line, the number of female with pay is a smaller % of the
female population than the % in male population. (the housewife model is
still unbalanced with a househusband)
 * many big pays are to old workers, whose distribution in gender is not
the same as for young ones. (hint: the raw statistic should also be
tabulated by age, but this is not available)


And last:
 * it take only into account employee, not employer and self-enterprise.
The gender distribution on these two latter category can be very different.
