United States of America in 1998

As of 1998, the United States of America counted 276,119,332 inhabitants. A decade earlier, in 1988, the population was 248,393,235; it has grown by 11.2% since. Half of the population was younger than 34.9 years; 21.4% were children under 15 and 12.3% were 65 or older. The near-vertical sides of the pyramid indicate a stationary age structure, with births roughly balancing the passage of cohorts into older age.

The bulge of cohorts born between 1946 and 1964 — the post-war baby boom — is the defining feature of the United States pyramid, visible as it moves up the age scale over the decades.
