Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.

Part 3. Exercise
During the last decade, Philadelphia experienced a large shift in its age profile. In 2000, the city's population pyramid had a largely stationary shape. In 2013, the city took on an expansive pyramid shape, with an increase in the three millennial age groups, 20 to 24, 25 to 29, and 30 to 34. The city's 25- to 29-year-old age group was the city's largest age cohort. According to the 2010 Census, 343,837 (22.5%) were under the age of 18; 203,697 (13.3%) from 18 to 25; 434,385 (28.5%) from 25 to 44; 358,778 (23.5%) from 45 to 64; and 185,309 (12.1%) who were 65 years of age or older. The median age was 33.5 years. For every 100 females there were 89.4 males. For every 100 females age 18 and over, there were 85.7 males. The city had 22,018 births in 2013, down from a peak 23,689 births in 2008. Philadelphia's death rate was at its lowest in at least a half-century, 13,691 deaths in 2013. Another factor attributing to the population increase is Philadelphia's immigration rate. In 2013, 12.7 percent of residents were foreign-born, just shy of the national average, 13.1 percent.
Answer:
What is the city's largest age group?
