A percentage point or percent point is the unit for the arithmetic difference between two percentages. For example, moving up from 40 percent to 44 percent is an increase of 4 percentage points (although it is a 10-percent increase in the quantity being measured, if the total amount remains the same).

Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. [14] The last 50 years have seen a yet more rapid increase in the rate of population growth [14] due to medical advances and substantial increases in agricultural productivity, particularly beginning in the 1960s, [15] made by the Green ...
In 2008, Ukraine emerged from lowest-low fertility, and the upward trend continued to 2012, with population decline slowing year after year. If early 2010s trends had persisted, the population could have returned to positive growth later that decade. Similar trends occurred in Russia and Belarus, which experienced population growth in the 2010s.
He cited one study as putting the Arab population growth attributable to immigration between 1922 and 1931 at 7%, meaning that 4% of the Arab population in 1931 was foreign-born, while noting another estimate [125] put the growth in the Arab population attributable to immigration at 38.7%, which would mean that 11.8% of the Arab population in ...
In 2003, the percentage of the adult population who had completed high school or had not completed high school but obtained a GED increased for the first time since 2000, when it was 84 percent. This increase follows a general trend that the Current Population Survey has shown since educational attainment was first measured in 1947. [3]
A substantial fraction of the water supply for some regions consists of water extracted from water stored in stocks, and when withdrawals exceed recharge, stocks decrease. By some estimates, as much as 30 percent of total water used for irrigation comes from unsustainable withdrawals of groundwater, causing groundwater depletion .
The level of support for evolution among scientists, the public, and other groups is a topic that frequently arises in the creation–evolution controversy, and touches on educational, religious, philosophical, scientific, and political issues.
[83] [84] The growth rate is maximized at about −13 °C (9 °F), and becomes vanishingly small much below −30 °C (−22 °F) as supercooled water droplets become rare. For this reason, hail is most common within continental interiors of the mid-latitudes, as hail formation is considerably more likely when the freezing level is below the ...
