Passage: According to the 2010 United States Census, the City and County of Denver contained 600,158 people and 285,797 households. The population density was 3,698 inhabitants per square mile (1,428/km²) including the airport. There were 285,797 housing units at an average density of 1,751 per square mile (676/km²). However, the average density throughout most Denver neighborhoods tends to be higher. Without the 80249 zip code (47.3 sq mi, 8,407 residents) near the airport, the average density increases to around 5,470 per square mile.Age distribution was 22.0% under the age of 18, 10.7% from 18 to 24, 36.1% from 25 to 44, 20.0% from 45 to 64, and 11.3% who were 65 years of age or older. The median age is 33 years. Overall there were 102.1 males for every 100 females, but in 2015 for the category of never-married ages 25 to 34, there were 121.4 males for every 100 females. Due to a skewed sex ratio wherein single men outnumber single women, some protologists have nicknamed the city as Menver.
Question: Which age group populated Denver less, those under the age of 18 or 18 to 44?
answer:
span

question:
Passage: The Hotak dynasty  was an Afghan monarchy of the Ghilji Pashtuns, established in April 1709 by Mirwais Hotak after leading a successful revolution against their declining Persian Safavid overlords in the region of Loy Kandahar  in what is now southern Afghanistan. It lasted until 1738 when the founder of the Afsharid dynasty, Nader Shah Afshar, defeated Hussain Hotak during the long siege of Kandahar, and started the reestablishment of Iranian suzerainty over all regions lost decades before against the Iranian archrival, the Ottoman Empire, and the Russian Empire. At its peak, the Hotak dynasty ruled briefly over an area which is now Afghanistan, Iran, western Pakistan, and some parts of Tajikistan and Turkmenistan. In 1715, Mirwais died of a natural cause and his brother Abdul Aziz succeeded the monarchy. He was quickly followed by Mahmud who ruled the empire at its largest extent for a mere three years. Following the 1729 Battle of Damghan, where Ashraf Hotak was roundly defeated by Nader Shah, Ashraf was banished to what is now southern Afghanistan with Hotak rule being confined to it. Hussain Hotak became the last ruler until he was also defeated in 1738.
