Pyramid 1: Sudan
High birth rates (4.9 million averages) = proportional to population. Concave shape.
High infant mortality rates (signifies a high IMR)
Life expectancy extremely low, minimum make it to 100+.
For every 100 male, 97 female.
No breaks in the slope.
Expanding.
No migration evidence.
Pyramid 2: Brazil
Slight high birth rates, low compared to previous years
Convex shape
Stable infant mortality rates.
Low life expectancies
For every 100 male, 98 female
No breaks in the slope
Stable
No migration evidence
Pyramid 3: China
Low birth rates proportional to population.
Convex shape
Low infant mortality rates, due to low birth rates.
Slight high life expectancy, not many making to 100+.
Slight larger number of males than females, 100 males, 95 females. Early years contracted in relation to late years – One Child Policy. Contracting, low birth rates in relation to elderly population. No migration evidence, possibly 25-29.

Pyramid 4: United States
Birth rates are stable compared to previous years, relatively low in proportion to population. Convex shape.
IMR stable, no major losses.
Stable life expectancy, many making it past 70.
For every 100 men, 98 females.
35-39, probably Vietnam War decreased fertility rates.
Stable.
No clear evidence of migration.
