abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. The late 1980s saw a recession adversely affecting the city's economy.

Since the 1990s, as a result of the recession, Houston has made efforts to diversify its economy by focusing on aerospace and health care/biotechnology and by reducing its dependence on the petroleum industry. In 1997, Houstonians elected Lee P. Brown as the city's first African American mayor.

In June 2001, Tropical Storm Allison dumped up to 40 inches (1,000 mm) of rain on parts of Houston, causing the worst flooding in the city's history; the storm cost billions of dollars in damage and killed 20 people in Texas. By December of that same year, Houston-based energy company Enron collapsed into the third-largest ever U.S. bankruptcy during an investigation surrounding fabricated partnerships that were allegedly used to hide debt and inflate profits.

In August 2005, Houston became a shelter to more than 150,000 people from New Orleans who evacuated from Hurricane Katrina. One month later, approximately 2.5 million Houston area residents evacuated when Hurricane Rita approached the Gulf Coast, leaving little damage to the Houston area.
