Why compare these two starting points?

Nigeria and the United States illustrate a birth-weight comparison that may look quite different after switching to population weights. The ratio describes inputs, not the value of a life or the prospects of a particular household. Try each starting point and inspect the first events; do not use a few fictional deaths or careers to infer real-world national outcomes.

For a concrete comparison, first select Nigeria directly and read the fictional birth card, then select the United States in a new run. A different family, school or ending is a generated story. Keep those anecdotes separate from the population and annual-birth ratios shown here; neither ratio validates the mortality model.
