Between 1968 and 1990, the Consumer Price Index went from 34.8 to 130.7.
Cumulatively, prices increased 275.6%, which works out to an average of
6.20% per year. Put differently, a dollar in 1968 bought what
$0.27 buys in 1990.
Consumer prices rose 4.2% in 1968, up sharply from 1967’s
3.1% and the fastest pace in 17 years, as Vietnam War spending and a tight
labor market pushed inflation higher despite the Federal Reserve’s
earlier tightening. The year was marked by political violence: Martin
Luther King Jr. was assassinated on a motel balcony in Memphis on April
4, touching off rioting in more than 100 cities, and Robert F. Kennedy was
shot in Los Angeles on June 5, moments after winning California’s
Democratic presidential primary, and died the next day. Washington tried
to answer the inflation problem directly that June 28, when Congress
passed a 10% income tax surcharge, the Revenue and Expenditure Control
Act, temporarily raising taxes and cutting spending to cool an economy
overheated by war and Great Society outlays; prices kept accelerating
anyway. The cost of living rose in smaller, more visible ways too:
first-class postage climbed to 6 cents that January 7, and the minimum
wage rose to $1.60 an hour that February 1, the final step of the
increase Congress had set two years earlier. Consumer prices finished
1968 251.5% above their 1913 level.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1968 spending costs in 1990, by category:

Not shown because the BLS began these indexes after 1968: recreation (1993–), education & communication (1993–).
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
