I'm trying to find out what is the average weight and bodyfat of a pretty good healthy 47-year-old woman?
The average weight for a 50 to a 52 year old is 150 pounds.
The average weight for a 5'4" woman in the range from 45 to 54 years old is between 135 lb and 155 lb or in other words 145 lb ± 10 lb. There is considerable variability based on nationality and ethnic origin.
Think about their hair.
It seems average female weight (adult) is between 138 - 164 lbs.

The average weight of a woman who is 5'3'' is between about 110-135 lbs. Differences can be cause by body type, muscle mass, certain medical conditions and medication, along with other factors. Weights within a few pounds of this scale are usually "average" or "healthy", too.
