Demographic estimates

In the mid to late twentieth century, Lyncourt was the biggest destination for Italian American families looking to migrate to the suburbs. This continued until the early twenty first century, until an eventual slowdown. Still, over 3% of people living in Lyncourt speak both Italian and English, this is greater than 99% of the country. During the early 2000s, Lyncourt was one of the most densely populated Italian American areas in the nation. This culture has greatly influenced the neighborhood, as many families still hold on to their ancestry practices.
