Highlights
The world's population has reached 8 billion according to the United Nations.
It took 125 years to reach 2 billion people, and only a short time after to add another billion.
India is expected to become the most populous nation in the world, surpassing China next year.
By 2050, India will have 300 million more people than China.
India currently struggles with resources and has over a quarter of the world's undernourished people.
More than half of the projected population increase over the next 30 years will come from just eight countries.
The eight countries contributing to the population increase include India, Pakistan, the Philippines, Tanzania, Egypt, Nigeria, Ethiopia, and the Democratic Republic of the Congo.
Sub-Saharan Africa is expected to have the most rapid growth, with its population expected to double over the next 30 years.
Family sizes in Africa are a significant factor, with 4.6 births per woman, twice the global average.
The UN sees Africa entering a period of demographic dividend due to a large working-age population.
One third of the world's droughts occur in Africa, and parts of the region are affected by food insecurity due to strained resources and climate change.
Europe and North America are expected to reach peak population growth by the late 2030s and then start to decline.
By 2050, one of every four people in Europe and North America will be over the age of 65.
An aging population will put more pressure on healthcare systems and reduce the number of individuals contributing to the economy.

Climate change will also impact migration, as seen in the Philippines where sea levels are rising alongside population growth.

WASHINGTON WITH DETAILS.
THANKS.
>>> THERE ARE NOW 8 BILLION
PEOPLE ON THE PLANET, ACCORDING
TO THE UNITED NATIONS, LANA
ZACH JOINS NOW WITH MORE ON
WHAT THIS MEANS.
>> Reporter: THIS IS JUST HOW
HISTORICALLY LANDMARK THIS IS.
IT TOOK 125 YEARS TO REACH 2
BILLION PEOPLE ON THE PLANET
BUT IT TOOK ONLY UNTIL NOW TO
ADD ONE MORE ALIEN.
WE LOOK AT WHERE THE LATEST
SHIFTS ARE HAPPENING.
NEXT YEAR, INDIA WILL BECOME
THE MOST POPULOUS NATION IN THE
WORLD, SURPASSING EVEN CHINA.
BY 2050, INDIA WILL HAVE 300
MILLION MORE PEOPLE THAN CHINA,
ON A NATION THAT ALREADY
STRUGGLES WITH RESOURCES BUT
ERE IS A STAGGERING STATISTIC
FOR YOU.
INDIA IS HOME TO MORE THAN A
QUARTER OF ALL THE
UNDERNOURISHED PEOPLE WORLDWIDE
RIGHT NOW.
MORE THAN HALF OF THE PROJECTED
INCREASE OF THE POPULATION OVER
THE NEXT 30 YEARS IS GOING TO
BE COMIG FROM JUST EIGHT
COUNTRIES.
THEY ARE, IN ADDITION TO INDIA,
PAKISTAN, THE PHILIPPINES,
TANZANIA, EGYPT, NIGERIA,
ETHIOPIA, AND THE DEMOCRATIC
REPUBLIC OF THE CONGO.
SOME OF THE MOST RAPID GROWTH
IS EXPECTED IN SUB-SAHARAN
AFRICA.
THE POPULATION THERE IS
EXPECTED TO DOUBLE OVER THE
NEXT 30 YEARS, REACHING 2
BILLION PEOPLE.
FAMILY SIZES A BIG FACTOR.
4.6 BIRTHS, THAT IS TWICE THE
CURRENT GLOBAL AVERAGE.
THE UN'S AS THE REGION IS ABOUT
TO ENTER A PERIOD OF
DEMOGRAPHIC DIVIDEND WHICH
MEANS THE LARGE WORKING AGE
POPULATION FOR AFRICA.
THIS IS ESPECIALLY IMPORTANT,
SINCE ONE THIRD OF THE WORLD'S
DROUGHTS OCCUR THERE, AND PARTS
OF THIS REGION ARE EFFECTED BY
PUTIN'S -- FOOD INSECURITY DUE
TO STRAINED RESOURCES ON
CLIMATE CHANGE.
BUT, LET'S TALK ABOUT THE AREAS
OF THE WORLD THAT ARE GOING TO
DROP.
THAT IS EUROPE AND NORTH
AMERICA.
THEY ARE GOING TO REACH PEAK
POPULATION GROWTH BY ABOUT THE
LATE 2030S, AND THEN START TO
DECLINE, ESPECIALLY AS THE
CURRENT POPULATION GETS OLDER.
LET'S TALK ABOUT US, HERE, IN
NORTH AMERICA.
BY 2050, IN EUROPE AND NORTH
AMERICA, ONE OF EVERY FOUR
PEOPLE WILL BE OVER THE AGE OF
65.
IN ALL SERIOUSNESS, IT MEANS
MORE PRESSURE ON EXISTING
HEALTHCARE SYSTEMS, AND FEWER
INDIVIDUALS CONTRIBUTING TO THE
ECONOMY WHICH IS WHY THE U.N.
SAYS THE SOLE DRIVER IN
POPULATION GROWTH OF HIGH
INCOME COUNTRIES OVER THE NEXT
SEVERAL DECADES WILL BE BE
CLOSE BECAUSE OF MIGRATION.
CLIMATE CHANGE WILL IMPACT
MIGRATION AS WELL.
IF YOU LOOK TO THE PHILIPPINES,
FOR EXAMPLE, THE POPULATION
THERE WILL GROW RAPIDLY, BUT
THE SEA LEVEL IS ALSO RISING,
AND THAT
