Quality of life
In a study conducted by American City Business Journals in 2004, Los Alamos County topped the list as the best place to live in the United States in terms of quality of life. This was attributed to the high levels of job stability, income and education of Los Alamos residents, many of whom are employed as scientists and engineers at the Los Alamos National Laboratory. The county has one of the highest number of PhDs per capita and the 2011 median household income of $110,204 per year is the second highest among all the counties in the U.S. In per capita income, Los Alamos County ranks 1st in New Mexico and 7th in the United States, and has the second-lowest level of poverty in the United States, and the lowest level of child poverty. Other factors contributing to Los Alamos's high quality-of-life index were the access to affordable housing and short commuting times.
In 2021, Los Alamos County was judged by the U.S. News & World Report to be the healthiest of 3,143 counties and county-equivalents of the United States based on 84 different factors. Residents of the county lived 83.4 years on the average compared to the U.S. average of 77.5 years.

Current energy resources
Starting in 1985, Los Alamos County, including both the White Rock and Los Alamos communities, has shared energy resources with the Los Alamos National Laboratory.
Future energy resources
Both Los Alamos County and the Los Alamos National Laboratory are trying to reduce their respective carbon emissions in order to help mitigate the continually worsening dangers of climate change. In 2015, Los Alamos County joined with the Utah Associated Municipal Power Systems in the Carbon Free Power Project. The Project plans to use NuScale Power’s Small Module Reactor design to provide nuclear energy to counties across the United States. Los Alamos’ history is tied to nuclear energy, which has an environmental impact comparable to that of renewables as a source of domestic power. This is true of both large and small module reactors.
Politics
Formerly solidly Republican, Los Alamos County has voted Democratic in the four most recent presidential elections. It has seen high percentages of third-party votes in years with major third-party candidates, such as with John B. Anderson in 1980, Ross Perot in 1992 and 1996, and Gary Johnson in 2012 and 2016.
