The given graph delineates the percentage of female workers and workers aged 50 or above in the United Kingdom workforce. This has been demonstrated by plotting the proportion of the population in UK along the successive decades spanning from 1971 to 2019. Notably, the number of female members in the UK workforce was significantly higher than the number of their counterparts whose ages were 50 or above.
In the decade, 1971 to 1980, the number of women in the workforce was at its nadir, falling at only 37% of the total manpower. This number rose with time, albeit slowly, reaching its peak in the year 2019, at 47% which is nearly a half of the total proletariat. This increment underscores a significant trend towards gender parity in employment over the years.
Conversely, the number of employed citizens above the ages of 50, was non existent, before the 90s period. This prevalent trend of an early retirement shifted modestly as the number of senior citizens in the UK workforce started growing from 21% in the years, 1990 to 2000, and peaking in the 2010 era, reaching its maximum in the year 2019, which is at 32%, reflecting a notable increase in the retention and participation of older individuals in the labor market.
