There are lots of towns named Newark in the world. Many of them are quite small. The Newark in South Dakota now has a zero population, and the Newark in Nebraska has a population under 100 people. Determining how many Newarks there actually are goes to show how inexact record-keeping still is. I was trying to find the Newark in Georgia, and the internet tried to book me a flight from New Jersey to Atlanta even though its Newark is close to the Florida border in the southern part of the state, too small to be on state maps, and without an airport near it.
There are said to be 17 Newarks in the United States, one in England, an unfindable Newark in the Orkney Islands north of Scotland, and an unfindable Newark in Ontario, Canada. Finding particular town names is still far from an exact science or even a demographic possibility.
The indisputable fact is that the largest Newark in the USA where there are more Newarks than anywhere else in the world is the town in New Jersey with an airport that serves New York City. Almost 300,000 people live there. Probably more. The 2nd largest Newark is in Ohio. Almost 50,000 live in its Newark that is south east of Columbus, its capital. The 3rd largest Newark is in California. It’s on the other side of the bay from San Francisco near Hayward. The 4th largest Newark is a surprise. It’s a city in small Delaware, which has only 3 counties. Its Newark contains about 31,500 people. The Newark in New York State is the 5th largest one with a population of only 9,000 or so. It’s near Rochester.
The name Newark comes from England where the town of Newark is said to be in Nottinghamshire. A church pastor eventually caused many towns to have this town name because of a city called Newark-on-Trent. Locals often call theirs towns “Nork”.
