Question: Dayton, Newark is part of the county in New Jersey having what population as of 2016?
Context: Interstate 280 (abbreviated I-280) is a 17.85 mi Interstate Highway in the U.S. state of New Jersey.  It provides a spur from I-80 in Parsippany-Troy Hills, Morris County to Newark, and I-95 (the New Jersey Turnpike) in Kearny, Hudson County.  In Kearny, access is provided toward the Holland Tunnel and Lincoln Tunnel to New York City.  The western part of the route runs through suburban areas of Morris and Essex counties, crossing the Watchung Mountains.  Upon reaching The Oranges, the setting becomes more urbanized and I-280 runs along a depressed alignment before ascending again in Newark.  I-280 includes a lift bridge, the William A. Stickel Memorial Bridge over the Passaic River between Newark and Harrison.  The highway is sometimes called the Essex Freeway.  I-280 interchanges with several roads, including the Garden State Parkway in East Orange and Route 21 in Newark. Newark Liberty International Airport Station (also known as Newark International Airport Station) is a railroad station on the Northeast Corridor (NEC) in Newark, New Jersey.  The station provides access to Newark Liberty International Airport (EWR) via the AirTrain monorail which connects the station to the airport's terminals and parking areas.  It is served by New Jersey Transit's (NJT) Northeast Corridor Line and North Jersey Coast Line and Amtrak's "Northeast Regional" and Keystone Service trains.  The station, located in the Dayton neighborhood of the city, has no pedestrian access, bus service, parking facility, or drop-off area. Interstate 78 (I-78) is an east–west route stretching from Union Township, Lebanon County, Pennsylvania to New York City.  In New Jersey, I-78 is called the Phillipsburg–Newark Expressway and the Newark Bay Extension of the New Jersey Turnpike.  The highway runs for 67.83 mi in the northern part of the state of New Jersey from the Interstate 78 Toll Bridge over the Delaware River at the Pennsylvania state line in Phillipsburg, Warren County east to the Holland Tunnel under the Hudson River at the New York state line in Jersey City, Hudson County.  The Phillipsburg-Newark Expressway portion of I-78, formally called the Lightning Division Memorial Highway, runs from the Phillipsburg area east across rural areas of western New Jersey before entering suburban areas in Somerset County.  The road crosses the Watchung Mountains, widening into a local-express lane configuration at Route 24 as it continues through urban areas to Newark.  Here, I-78 intersects the mainline of the New Jersey Turnpike (I-95) and becomes the Newark Bay Extension, crossing the Newark Bay Bridge and continuing to Jersey City.  The route, along with Route 139, follows a one-way pair of surface streets to the Holland Tunnel. Dayton is a neighborhood within the city of Newark in Essex County, New Jersey, United States.  It is part of the city's south ward and was named after Jonathan Dayton.  The area is bounded on the north by Peddie Street (Thomas Baldwin Peddie), on the east by Newark Liberty International Airport, on the south by Elizabeth and on the west by Elizabeth Avenue.  The main road through the neighborhood is Frelinghuysen Avenue, but it is surrounded by U.S. Route 1/9, Interstate 78 and U.S. Route 22.  The neighborhood of Dayton encompasses all of Weequahic Park, the second largest Park in Newark.  The park includes an 80 acre lake (the largest in Essex County), a golf course and an old racetrack now used for jogging.  The park has gospel and jazz concerts at night.  The park is bisected by US 22 and the larger, southern section of the park (including Weequahic Lake) is easily accessible to Dayton. Essex County is a county in the northeastern part of the U.S. state of New Jersey.  As of the 2016 Census estimate, the county's population was 796,914, making it the state's third-most populous county, an increase of 1.7% from the 2010 United States Census, when its population was enumerated at 783,969, in turn a decrease of 1.2% (9,664 fewer residents) from the 793,633 enumerated in the 2000 Census.  In 2010, the county dropped down to third-largest, behind Middlesex County, and was one of only two counties in the state to see a decline between 2000 and 2010 (Cape May County being the other).  Its county seat is Newark.  It is part of the New York Metropolitan Area. Eagle Academy for Young Men of Newark is an all boys' public school in Newark in Essex County, New Jersey, United States, operating as part of the Newark Public Schools.  The Eagle Academy Foundation supports the educational programs of this school and other all-boys' schools in New York City.

U.S. Route 1/9 (US 1/9) is the 31.01 mi long concurrency of US 1 and US 9 from their junction in Woodbridge Township, Middlesex County, New Jersey north to New York City.  The route is a multilane road, with some freeway portions, that runs through urbanized areas of northern New Jersey adjacent to New York City.  Throughout most of its length in New Jersey, the road runs near the New Jersey Turnpike/Interstate 95 (I-95).  In Fort Lee, US 1/9 merges onto I-95 and crosses the Hudson River on the George Washington Bridge, where the two U.S. routes split a short distance into New York.  US 1/9 intersects several major roads, including I-278 in Linden, Route 81 in Elizabeth, I-78 and US 22 in Newark, Route 139 in Jersey City, Route 3 and Route 495 in North Bergen, and US 46 in Palisades Park.  Between Newark and Jersey City, US 1/9 runs along the Pulaski Skyway.  Trucks are banned from this section of road and must use US 1/9 Truck.  The concurrency between US 1 and US 9 is commonly referred to as "1 and 9".  Some signage for the concurrency, as well as the truck route, combines the two roads into one shield, separated by a hyphen (1-9) or an ampersand (1&9). Route 21 is a highway in northern New Jersey, running 14.35 mi from the Newark Airport Interchange with U.S. Route 1/9 and U.S. Route 22 in Newark, Essex County to an interchange with U.S. Route 46 in Clifton, Passaic County.  The route is a four- to six-lane divided highway known as McCarter Highway on its southern portion in Newark that serves as a connector between the Newark and Paterson areas, following the west bank of the Passaic River for much of its length.  It also serves as the main north–south highway through the central part of Newark, connecting attractions in downtown Newark with the Newark Liberty International Airport.  The portion of Route 21 through Newark is a surface arterial that runs alongside the elevated Northeast Corridor rail line through the southern part of the city and continues north through Downtown Newark while the portion north of Downtown Newark is a freeway.  Route 21 intersects many major roads including Interstate 78, Route 27, and Interstate 280 in Newark, Route 7 in Belleville, and Route 3 in Clifton. The Newark Bay Bridge, officially the Vincent R. Casciano Memorial Bridge, is a steel through arch bridge that is continuous across three spans.  It crosses Newark Bay and connects the cities of Newark (in Essex County) and Bayonne (in Hudson County) in New Jersey, United States.  It was completed April 4, 1956, as part of the New Jersey Turnpike's Newark Bay (Hudson County) Extension, with a ribbon-cutting ceremony led by Governor of New Jersey Robert B. Meyner. New Jersey Medical School (NJMS)—also known as Rutgers New Jersey Medical School—is a graduate medical school of Rutgers University that is part of the division of Biomedical and Health Sciences.  NJMS is the oldest school of medicine in New Jersey.  The school of medicine was founded in 1954 as the Seton Hall College of Medicine and Dentistry, established under the auspices of the Roman Catholic Archdiocese of Newark, in Jersey City, New Jersey.  On August 6, 1954, the College was incorporated as a legal entity separate from Seton Hall University, but with an interlocking Board of Trustees.  The first class of 80 students was admitted to the four-year MD program in September 1956, becoming only the sixth medical school in the New York City metropolitan area.  In 1965, the institution was acquired by the State of New Jersey, renamed the New Jersey College of Medicine and Dentistry (NJCMD), and relocated to Newark, New Jersey.  With the passing of the Medical and Dental Education Act of 1970, signed into law by Governor William T. Cahill on June 16, the College of Medicine and Dentistry of New Jersey (CMDNJ) was created, merging NJCMD with the two-year medical school established at Rutgers University in 1961, under a single board of trustees.
