Havertown is a residential suburban unincorporated community in Haverford Township, Delaware County, Pennsylvania, United States, approximately 9 miles west of the center of Philadelphia. Havertown's ZIP Code is 19083. Havertown is notable for being the birthplace of Swell Bubble Gum, which closed its doors in late 2004, and was demolished in 2011. The Swell site in 2013 will be the home of the brand new Haverford Township Area YMCA. Havertown is one of the few towns that have a Superfund site caused by a timber mill that finished telephone poles; the chemical that was used to coat the telephone poles was dumped into the ground. Coincidently, these two sites are directly across the street from one another.
Havertown is also known for its large Irish-American population. Many Irish-Americans still live there today. According to the 2000 US Census, Haverford Twp. ranks in the top 60 of census-recognized municipalities nationwide in percentage of population with Irish ancestry. The neighborhood takes pride in its distinct Irish heritage and is home to many Irish bars and shops. Many locals still reverentially (and only half-jokingly) refer to Havertown as the "33rd county" (of Ireland). For these reasons the neighborhood remains a very popular destination for Irish immigrants. Of the 51,560 residents, 11,182 noted "Irish" as their first reported ancestry. Havertown is home to over 30 outdoor parks and playing fields. The town also provides other recreation facilities including the Haverford Township Free Library, an outdoor skate park, and the Haverford Township Skatium, a multi-use ice rink for Havertown residents. The town is guarded and watched over by the Haverford Township Police Department and is under the protection of five fire companies: Bon Air, Brookline, Llanerch, Manoa, and Oakmont.
