Children Born in 1926.—The; boys are 1.5 inches taller and
2.9 lbs. heavier on the average than the girls. The average minimum
weight of the boys is 2.3 lbs. more and their average
minimum height 0.2 inches taller than the corresponding figures
for the girls. The average maximum weight of the boys is 1.4
lbs. more and their average maximum height 0.4 inches taller
than for the girls. Boys at this age are accordingly as a group
heavier and taller than girls, and exhibit a smaller range between
the extremes. This finding is much the same as for 1930, dealing
with children born in 1925, though the variations were not so
large.
Children Born in 1925.—The boys are 0.5 inches taller and
1.6 lbs. heavier on the average than the girls. The average minimum
weight of the boys is 1.8 lbs. more than their average
minimum height 0.4 inches taller than the corresponding figures
for the girls. The average maximum weight of the boys is 1.5
lbs. more and their average maximum height 1.0 inches taller
than for the girls. Although heavier, the boys show a general
retardation in the rate of increase in stature. These children
belong to the same group as were dealt with in last year's report,
and comparison shows that the girls are showing more rapid
growth than the boys.
Children Born in 1923.—The boys are 0.5 inches taller and
2.2 lbs. heavier on the average than the girls. The average minimum
weight of the boys is 1.9 lbs. more and their average
minimum height 0.4 inches taller than the corresponding figures
for the girls. The average maximum weight of the boys is the
same as the girls and their average maximum height 0.2 inches
taller than for the girls. This group of children are similar
in their relationships to the 1924 group.
Children Born in 1919.—The boys in this group were 1.0
inches shorter and 1.4 lbs. lighter on the average than the girls.
The average minimum weight of the boys is 2.1 lbs. greater and
their average minimum height 0.3 ins. shorter than the girls.
The average maximum weight of the boys is, however, 6.6 ibs.
lighter and their average maximum height 0.4 ins. shorter than
for the girls. In this group as a whole the boys are shorter and
lighter than the girls, but the former are a more uniform group:
the girls exhibiting greater fluctuations around the mean average,
The average minima of heights and weights are taken by
selecting the shortest and lightest scholar in any particular group
for each school and taking the average of the figures so obtained.
The average maxima heights and weights are also obtained in
the same way.
