Why this differs from numbers you may have seen elsewhere
Two things change the answer: which year you use, and whether the denominator is births or people alive. We use births in the same year as the numerator, over all 237 locations the UN publishes. A figure sampled over people alive answers a different question — the odds a living person is from that country — and will always be larger for large countries.
The weights used for sampling sum to 132,110,261 births, so no location is silently excluded.
