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.
