According to a 2013 article in The Economist, surveys of political attitudes among Millennials in the United Kingdom suggest increasingly liberal attitudes with regard to social and cultural issues, as well as higher overall support for classical liberal economic policies than preceding generations. They are more likely to support same-sex marriage and the legalization of drugs.
The Economist parallels this with Millennials in the United States, whose attitudes are more supportive of social liberal policies and same-sex marriage relative to other demographics, though less supportive of abortion than Gen X were in the early 1990s. They are also more likely to oppose animal testing for medical purposes.
A 2014 poll for the libertarian Reason magazine suggested that US Millennials were social liberals and fiscal centrists more often than their global peers. The magazine predicted that millennials would become more conservative on fiscal issues once they started paying taxes.
William Strauss and Neil Howe projected in their 1991 book Generations that the U.S. Millennial population would be 76 million. Later[when?] Neil Howe revised the number to over 95 million people (in the U.S.). As of 2012, it was estimated that there were approximately 80 million U.S. Millennials. The estimated number of the U.S. Millennials in 2015 is 83.1 million people.
