Input (English): Passage: In 2016, there were 122,051 people residing in Syracuse, located in the province of Syracuse, Sicily, of whom 48.7% were male and 51.3% were female. Minors (children ages 18 and younger) totalled 18.87 percent of the population compared to pensioners who number 16.87 percent. This compares with the Italian average of 18.06 percent (minors) and 19.94 percent (pensioners). The average age of Syracuse resident is 40 compared to the Italian average of 42. In the five years between 2002 and 2007, the population of Syracuse declined by 0.49 percent, while Italy as a whole grew by 3.56 percent. The reason for decline is a population flight to the suburbs, and northern Italy.
