At least 1,634 people were executed in 25 countries in 2015. This represents a stark increase on the number of executions recorded I 2014 of more than 50%; in 2014 Amnesty International recorded 1,061 executions in 22 countries worldwide.
This is the highest number of executions recorded in more than 25 years (since 1989).
Most executions took place in China, Iran, Pakistan, Saudi Arabia and the USA - in that order.
China remained the world's top executioner - but the true extent of the use of the death penalty in China is unknown as this data is considered a state secret; the figure of 1,634 excludes the thousands of executions believed to have been carried out in China.
Excluding China, almost 90% of all executions took place in just three countries - Iran, Pakistan and Saudi Arabia.
During 2015, 25 countries, about 1 in 10 of all countries worldwide, are known to have carried out executions - a rise from 22 in 2014. This number has decreased significantly from 2 decades ago (39 countries carried out executions in 1996).
140 countries worldwide, more than 2/3, are abolitionist in law or practice.
In 2015, 4 countries - Fiji, Madagascar, the Republic of Congo and Suriname - abolished the death penalty for all crimes. In total, 102 countries have done so - a majority of the world's states. In 2015, Mongolia also passed a new criminal code abolishing the death penalty which will come into effect later in 2016.
Commutations or pardons of death sentences were recorded in 34 countries in 2015. At least 71 people who had been sentenced to death were exonerated in 6 countries in 2015: China (1), Egypt (1), Nigeria (41), Pakistan (at least 21), Taiwan (1) and USA (6).
At least 1,998 death sentences were recorded in 61 countries in 2015, a decline from 2014 (at least 2,466 death sentences in 55 countries).
At least 20,292 people were on death row at the end of 2015.
The following methods of execution were used across the world: beheading, hanging, lethal injection and shooting.
Reports indicated that at least 9 people who were under 18 at the time of the crime for which they were sentenced to death were executed in 2015 - 4 in Iran and 5 in Pakistan.
In many countries where people were sentenced to death or executed, the proceedings did not meet international fair trial standards. In some cases this included the extraction of 'confessions' through torture or other ill-treatment, including in Bahrain, China, Iran, Iraq, North Korea and Saudi Arabia.
People continued to be sentenced to death and executed for offences that do not meet the "most serious crimes" threshold of "intentional killing" as set out in international law and standards. These offences included drug-related crimes in at least 12 countries in Asia and the Middle East, as well as committing "adultery" (Maldives, Saudi Arabia), economic crimes (China, North Korea, Viet Nam), "apostasy" (Saudi Arabia) and "insulting the prophet of Islam" (Iran).
At least 43 executions were carried out in 4 countries - compared to 46 executions in 3 countries in 2014.
Death sentences fell sharply from 909 in 2014 to 443 in 2015, mainly due to a decrease in Nigeria.
Chad, which had not executed anyone for more than a decade, resumed executions and put 10 people to death. The other 3 countries that carried out executions were Somalia, South Sudan and Sudan.
For the 7th consecutive year, the USA was the only country to carry out executions in the Americas region with, 28 people executed in 2015 (7 fewer than in 2014). This was the lowest number of executions recorded in a single year since 1991. 6 states executed in 2015 compared to 7 the previous year. The number of death sentences decreased from at least 72 in 2014 to 52 in 2015, the lowest number recorded since executions resumed in 1977. Only one other country in the region, Trinidad and Tobago, imposed death sentences in 2015.
At least 367 executions were carried out in 12 countries - a huge increase on the 32 executions in 9 countries recorded in 2014, almost exclusively due to the rise in Pakistan. This figure does not include executions carried out in China, where executions were still in the thousands. But the true extent of the use of the death penalty in China is unknown as data is treated as a state secret.
Pakistan put 326 people to death in 2015 after the country lifted a 6-year moratorium on the execution of civilians in December 2014, following the Taliban attack on a school in Peshawar. It is the highest number of executions Amnesty International has ever recorded for Pakistan.
Indonesia carried out 14 executions for drug-related offences, the 1st executions under President Joko Widodo.
It was impossible to confirm the real number of executions in North Korea.
Europe and Central Asia
Belarus - the only country in the region that executes - did not put anyone to death in 2015 but imposed 2 death sentences (compared to 3 executions and no death sentences in 2014).
Middle East and North Africa
At least 1,196 executions were carried out in 8 countries - a rise of 26% from the 945 executions recorded in 8 countries in 2014.
Iran alone accounted for 82% of all recorded executions in the region.
Saudi Arabia executed at least 158 people - a 76% increase on 2014 and the highest number recorded for Saudi Arabia since 1995.
Amnesty International could not confirm if executions took place in Syria.
