Aging Population

Just for the hell of it, I decided to find out what
happens to the number of workers as the general population ages. To
set this up, I took one of my old cities, deleted all housing, and then
when population was down to zero, replaced the housing plots. The housing
was developed to Ordinary Cottage level and then held there. Care was
taken to prevent population fluctuations due to warfare, disease, fire,
damage, poor sentiment, and acts of God.
Here's what happened:

At this point I got bored and gave it up. Despite the
occasional numerical glitch, the pattern is pretty clear.
Next I decided to see exactly how deleting and replacing
all housing would affect the labor situation. I went back to the end
of year 31, deleted all housing (leaving services in place) and sat
back to see what happened.

Before I was short 13 workers at the end of the 34th
year. Now I have 355 unemployed plus vacant housing. Notice that it
only took about a year and a half to get all services staffed.
When deleting all housing care must be taken to protect
the remaining structures from fire or collapse. This can be done by:
a -Going to Labor Overseer and setting Infrastructure to priority
#1.
b - Putting a few plots in each housing area before filling in the
remainder. Since settlers fill plots in the order in which they are
laid out, I want to make sure all areas get enough workers for fire
and architects without their having to wait in turn for large blocks
to fill up.
