Story hunting in birth, death data

Note: This post, originally published in 2010, is being updated regularly. It currently reflects final 2015 U.S. birth data and final 2015 U.S. death data, both available as of early 2017.

The U.S. government’s annual count of births and deaths is among the most basic of demographics, but tracking it is one of my little obsessions. I keep annual totals in a spreadsheet and get all gooey inside when I can add another year to the pile.

Year-over-year changes occasionally show a surprising upturn or drop that’s worth writing about, such as when U.S. births in 2014 showed an increase for the first time in seven years. Just as often, the new number’s less interesting. In June 2016, for example, the National Center for Health Statistics released data showing that the number of births in the U.S. dipped slightly in 2015. Not much change; probably not a story.

For that reason, it’s usually better to take a long-term view of demographic data. For example, below are the annual number of births and deaths from 1933 to 2015 plotted via the Google Charts API. Hover over the lines for the data:

It’s simple — just two fever lines. But it’s chock full of generational milestones that bear watching:

  • The first baby boomers — those born in 1946 — turned 70 in 2016.
  • The Gen Xers that follow are marching toward middle age, now in their mid 30s to early 50s. (Gen X poster boy Eddie Vedder of Pearl Jam hit the half-century mark in 2014.)
  • Meanwhile, the first of the Millennials — the “echo boomers” whose numbers peaked in 1990 — are in their early 30s.

Each generation brings a new sensibility to the stages of life, and the relative size and makeup of each group — not to mention its cultural context — gives journalists plenty of opportunity for storytelling. Two examples:

  • Much has been written about the big bump of post-World War II babies marching closer to retirement (maybe), Social Security, and the years where health care becomes a major concern. But what about the inevitable? Notice that the number of deaths in the U.S. has ticked up to about 2.6 million a year. Expect that to keep climbing as more Boomers head into the years where death rates rise dramatically. How will 4 million deaths annually affect the funeral home business, the ability to buy a cemetary plot, and the overall industry around end-of-life care?
  • Along with Gen X came the “baby bust,” the years of rapidly declining birth rates that led to all kinds of prognostications about the shrinking of America. That means our workforce now has a relative shortage of thirty- and forty-somethings. Does that mean more opportunity for Millennials to advance in the business world and less pressure for boomers to retire?

These sorts of trends are slow-burning, but they reflect data trends that exert hidden but massive force on our culture, much like the tides. The savvy data journalist keeps an eye on them not just for what they say this year but what they reveal over time.
