The statistic shows the global population as of mid-2020, sorted by age. In mid-2020, approximately 23.7 percent of the global population were aged between 10 and 24 years.

In 2020, the COVID-19 pandemic affected drastically all forms of human mobility, including international migration. Around the globe, the closing of national borders and severe disruptions to international travel obliged hundreds of thousands of people to cancel or delay plans of moving abroad. Hundreds of thousands of migrants were stranded, unable to return to their countries, while others were forced to return to their home countries earlier than planned, when job opportunities dried up and schools closed.

The world continues to experience an unprecedented and sustained change in the age structure of the global population, driven by increasing levels of life expectancy and decreasing levels of fertility. People are living longer lives, and both the share and the number of older persons in the total population are growing rapidly. Globally, there were 727 million persons aged 65 years or over in 2020. Since women live longer than men, on average, they comprise the majority of older persons, especially at advanced ages. Over the next three decades, the number of older persons worldwide is projected to more than double, reaching over 1.5 billion in 2050. All regions will see an increase in the size of the older population between 2020 and 2050.

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.

• 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. Since 1970, the number of people living in a country other than where they were born has tripled.

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. The report also focuses on projected life expectancy dif-ferences between the native-born and foreign-born populations. The mortality projections covered in this report are based on the first nativity-specific life ables and life expectancies to be published by the Census Bureau.

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.

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. The number of adults on parole increased 1.3% during 2020, from 851,000 on January 1, 2020 to 862,100 at yearend. Among all adult U.S. residents, 1 in 66 were supervised in the community at yearend 2020.

This report highlights trends in federal arrests and prosecutions by the country of citizenship of persons processed through the federal criminal justice system. It shows changes from 1998 through 2018. The report provides statistics on law enforcement and prosecutions along the U.S.-Mexico border, as well as in non-border areas. It shows the number of suspects arrested and prosecuted for both immigration and non-immigration offenses, including by their citizenship status. It details activities for all 94 federal judicial districts, while also separately detailing activities for the 5 districts along the U.S.-Mexico border. (See map on page 6.) The statistical findings in this report are based on data from the Bureau of Justice Statistics’ Federal Justice Statistics Program (FJSP).

Can it really be true that most people in jail are being held before trial? And how much of mass incarceration is a result of the war on drugs? These questions are harder to answer than you might think, because our country’s systems of confinement are so fragmented. The various government agencies involved in the justice system collect a lot of critical data, but it is not designed to help policymakers or the public understand what’s going on. As public support for criminal justice reform continues to build, however, it’s more important than ever that we get the facts straight and understand the big picture.

On any given day, over 48,000 youth in the United States are confined in facilities away from home as a result of juvenile justice or criminal justice involvement. Most are held in restrictive, correctional-style facilities, and thousands are held without even having had a trial. But even these high figures represent astonishing progress: Since 2000, the number of youth in confinement has fallen by 60%, a trend that shows no sign of slowing down.

What explains these remarkable changes? How are the juvenile justice and adult criminal justice systems different, and how are they similar? Perhaps most importantly, can those working to reduce the number of adults behind bars learn any lessons from the progress made in reducing youth confinement?
