The proportion would be the number of the sample (x) over the population size (n)

Here we have x = 59,969 and n= 461,299

P = x/n = 59969/461299

P = 0.13

Based on the number of people who are 65 and older, their proportion out of the total population is 13.00%.

Proportion refers to the percentage of something that the variable in question occupies.

In this case, the proportion of 65 years and older people is:

= People 65 and older / Total population x 100%

= 59,969 / 461,299 x 100%

= 13%

In conclusion, those aged 65 and above are 13% of the population.
