Sussex County, New Jersey in the context of "Per capita personal income in the United States"

Walpack Township is a township in Sussex County, in the U.S. state of New Jersey. As of the 2020 United States census, the township's population was 7, a decrease of 9 (−56.3%) from the 2010 census count of 16, which in turn reflected a decline of 34 (−82.9%) from the 41 counted in the 2000 census. Walpack Township was the smallest municipality by population and one of only four municipalities in New Jersey with a population under 100 as of the 2020 Census; it had the state's third-smallest population in the 2010 census, behind Tavistock (population 5) and the now-defunct Pine Valley (population 12), both in Camden County.

The township is named from a corruption of the Lenape Native American content word "wahlpeck," which means "turn-hole," or an eddy or whirlpool, a compound of two Native American words, "woa-lac" (a hole), and "tuppeck" (a pool), though other sources attribute the name to mean "very deep water" or "sudden bend of a stream around the base of a rock".

Dover is an active commuter railroad train station in the town of Dover, Morris County, New Jersey. Located at the end of electric service, Dover station serves as a secondary terminal of NJ Transit's Morristown and Montclair–Boonton Lines. Non-electric service continues west to Hackettstown on both lines. The next station to the west is Mount Arlington while the next station to the east is Denville.

The first train in Dover arrived on July 31, 1848, with the extension of the Morris and Essex Railroad from Rockaway, which opened just 27 days prior. The Delaware, Lackawanna and Western Railroad constructed the current station depot on Dickerson Street in 1901, opening on November 1. The station depot joined the National Register of Historic Places in 1980. Today the station serves as a major transportation center locally, it also serves commuters in nearby Sussex County.

New Jersey's 5th congressional district is represented by Democrat Josh Gottheimer, who has served in Congress since 2017. The district stretches across the entire northern border of the state and contains most of Bergen County, as well as parts of Passaic County and Sussex County.

Historically, most of the areas in the district have generally been favorable for Republicans. This is especially true of the western portion, which contains some of the most Republican areas in the Northeast. However, Bergen County has trended Democratic in recent elections, though not as overwhelmingly as in the more urbanized southern portion of Bergen County, this latter portion being in the ninth congressional district. Partly due to a strong performance in Bergen County, Josh Gottheimer unseated 14-year Republican incumbent Scott Garrett in 2016. This made Garrett the only one of the state's 12 incumbents to lose reelection that year and marked the first time a Democrat won this seat since 1930.
