Global Migration, By the Numbers: Who Migrates, Where They Go and Why

  • There are an estimated 272 million international migrants – 3.5% of the world’s population.
  • While most people leave their home countries for work, millions have been driven away due to conflict, violence
  • and climate change.
  • Most migrants come from India; the United States is the primary destination.

There are an estimated 272 million international migrants around the world. And while that equals just 3.5% of the world’s population, it already surpasses some projections for 2050.

How Many People Have Ever Lived on Earth?

Given a current global population of about 7.8 billion, the revised estimate means those alive in 2020 represent nearly 7% of the total number of people who have ever lived.

Living Longer: Historical and Projected Life Expectancy in the United States, 1960 to 2060

Throughout this report, we use the U.S. Census Bureau’s 2017 National Population Projections to examine potential mortality and life expectancy changes in the coming decades. To provide historical context, we draw extensively on life expectancy data from the National Center for Health Statistics (NCHS). The report includes projections of life expectancy from 2017 to 2060 and explores projected differences in mortality for men and women and for different race and Hispanic origin groups in the United States.

Probation and Parole in the United States, 2020

An estimated 3,890,400 adults were under community supervision at yearend 2020, which was a 6.6% decline from the 4,167,100 who were supervised in the community on January 1, 2020. This decline was solely driven by a reduction in people on probation, who made up the majority (79%) of the community supervision population. During 2020, the number of people on probation decreased from 3,330,200 to 3,053,700 (down 8.3%), the largest annual decline since the Bureau of Justice Statistics (BJS) began the probation collection in 1980.

States Can Shorten Probation and Protect Public Safety

More than 3.5 million, or 1 in 72, adults were on probation in the United States at the end of 2018—the most recent year for which U.S. Bureau of Justice Statistics (BJS) data is available—more than triple the number in 1980. Nationwide, on any given day, more people are on probation than in prisons and jails and on parole combined.
