4. Los Alamos County, New Mexico
> 5-yr. population change: -0.8%
> Nov. unemployment rate: 3.7%
> Poverty rate: 5.1%
> Life expectancy at birth: 83.5 years
Los Alamos County is less than 40 miles from Sante Fe, New Mexico’s capital city and about 90 miles north of Albuquerque, New Mexico’s largest city. The county’s economy is supported largely by the Los Alamos National Laboratory, a weapons development facility. The laboratory employs some 11,200 people from Los Alamos County and surrounding cities and towns and boasts a $2.45 billion annual budget.
Due in part to skill sets required to work at the laboratory, Los Alamos County has a well-educated population. Some 64.6% of county adults have a bachelor’s degree or higher, the third largest share of any U.S. county and more than double the share of American adults with similar education of 30.3%. The area’s high educational attainment is reflected in the county’s median household income. The typical Los Alamos household earns $105,902 a year, more than in all six other U.S. counties and about $45,700 more than the median income in Sandoval, the next wealthiest county in New Mexico.

> 5-yr. population change: +11.4%
> Nov. unemployment rate: 2.4%
> Poverty rate: 8.7%

The area’s high incomes are bolstered by the county’s well-educated labor force.
