From the 2011 Census, the Office for National Statistics published that Plymouth's unitary authority area population was 256,384; 15,664 more people than that of the last census from 2001, which indicated that Plymouth had a population of 240,720. The Plymouth urban area had a population of 260,203 in 2011 (the urban sprawl which extends outside the authority's boundaries). The city's average household size was 2.3 persons. At the time of the 2011 UK census, the ethnic composition of Plymouth's population was 96.2% White (of 92.9% was White British), with the largest minority ethnic group being Chinese at 0.5%. The white Irish ethnic group saw the largest decline in its share of the population since the 2001 Census (-24%), while the Other Asian and Black African had the largest increases (360% and 351% respectively). This excludes the two new ethnic groups added to the 2011 census of Gypsy or Irish Traveller and Arab. The population rose rapidly during the second half of the 19th century, but declined by over 1.6% from 1931 to 1951.

In 1592, and again in 1597, Toyotomi Hideyoshi, aiming to invade China () through Korea, mobilized an army of 160,000 peasants and samurai and deployed them to Korea. (See Hideyoshi's invasions of Korea, Chosen-seibatsu (?). Taking advantage of arquebus mastery and extensive wartime experience from the Sengoku period, Japanese samurai armies made major gains in most of Korea. Kato Kiyomasa advanced to Orangkai territory (present-day Manchuria) bordering Korea to the northeast and crossed the border into Manchuria, but withdrew after retaliatory attacks from the Jurchens there, as it was clear he had outpaced the rest of the Japanese invasion force. A few of the more famous samurai generals of this war were Kato Kiyomasa, Konishi Yukinaga, and Shimazu Yoshihiro. Shimazu Yoshihiro led some 7,000 samurai and, despite being heavily outnumbered, defeated a host of allied Ming and Korean forces at the Battle of Sacheon in 1598, near the conclusion of the campaigns. Yoshihiro was feared as Oni-Shimazu ("Shimazu ogre") and his nickname spread across not only Korea but to Ming Dynasty China. In spite of the superiority of Japanese land forces, ultimately the two expeditions failed (though they did devastate the Korean landmass) from factors such as Korean naval superiority (which, led by Admiral Yi Sun-shin, harassed Japanese supply lines continuously throughout the wars, resulting in supply shortages on land), the commitment of sizeable Ming forces to Korea, Korean guerrilla actions, the underestimation of resistance by Japanese commanders (in the first campaign of 1592, Korean defenses on land were caught unprepared, under-trained, and under-armed; they were rapidly overrun, with only a limited number of successfully resistant engagements against the more-experienced and battle-hardened Japanese forces - in the second campaign of 1597, Korean and Ming forces proved to be a far more difficult challenge and, with the support of continued Korean naval superiority, limited Japanese gains to parts southeastern Korea), and wavering Japanese commitment to the campaigns as the wars dragged on. The final death blow to the Japanese campaigns in Korea came with Hideyoshi's death in late 1598 and the recall of all Japanese forces in Korea by the Council of Five Elders (established by Hideyoshi to oversee the transition from his regency to that of his son Hideyori).
How many troops did Toyotomi Hideyoshi send to Korea?
****
The answer: 160,000

Around 10,200 BC the first fully developed Neolithic cultures belonging to the phase Pre-Pottery Neolithic A (PPNA) appeared in the fertile crescent. Around 10,700 to 9,400 BC a settlement was established in Tell Qaramel, 10 miles north of Aleppo. The settlement included 2 temples dating back to 9,650. Around 9000 BC during the PPNA, one of the world's first towns, Jericho, appeared in the Levant. It was surrounded by a stone and marble wall and contained a population of 20003000 people and a massive stone tower. Around 6,400 BC the Halaf culture appeared in Lebanon, Israel and Palestine, Syria, Anatolia, and Northern Mesopotamia and subsisted on dryland agriculture.
