Long Island’s Nassau County is one of the most expensive counties in America, but the area is made up of dozens of towns, villages, and hamlets with a huge range of home prices and average living costs.

So, how much does it cost to live on Long Island? To help you decide if Long Island is the right move for your family, this comprehensive guide covers the Long Island cost of living and explores the cost of living on Long Island by county and town.

Understanding the Cost of Living on Long Island – One Island with Four Counties, Two NYC Boroughs & Two that Make up “Long Island”

The Cost of Living Index (COLI) is one of the best ways to get an overall idea of how much it costs to live in a city or metropolitan area. Published by the Council for Community and Economic Research (C2ER), it’s calculated using cost data on 60 goods and services collected by more than 300 researchers at the local level. To understand how the cost of living index works, the average for all participating locations is equal to 100. Each city’s index is a percentage of the average for all places.

However, Long Island itself isn’t a city, nor is it a metro area. Instead, it’s part of the New York City metro area. Long Island is an island that’s made up of four counties:

  • Kings County or Brooklyn, a borough of New York City
  • Queens County or Queens, a borough of New York City
  • Nassau County
  • Suffolk County

When someone refers to Long Island, they are only referring to Suffolk and Nassau counties combined. Together, these counties make up a region, but not one that’s an official, independent body. Both counties are also home to several cities, towns, and villages that vary drastically in terms of cost. This means understanding the cost of living in Long Island becomes a bit more complicated.

To understand how much it costs to live on Long Island, we’ll look at Suffolk and Nassau County and major towns and villages.

Long Island Cost of Living Index

How much does it cost to live on Long Island? The cost of living index for Long Island is 147, or 47% higher than the national average. However, the COLI depends on the county and town or village.

The Bureau of Labor Statistics (BLS) tracks metrics that are also useful for understanding the cost of living. These reports are best for comparing how much you will pay to live in the NYC metro area compared to where you live now as the data is regional.

The Consumer Price Index (CPI) measures the average changes in prices consumers pay for goods and services in a region. Long Island is part of the New York-Newark-Jersey City area. A recent CPI update found regional prices were up 3.5% over a year. Prices for most services and goods declined, but food prices rose 3.4% and energy costs rose 17%. A 1% drop in electricity prices year-over-year was offset by a 9.8% increase in natural gas prices and a 40% increase in gas prices.

You can also look at the Consumer Expenditure Survey for the New York metro area. Households in the New York area spent $73,806 per year on average for 2018/2019. That compares to the average $62,395 expenditure for the typical U.S. household. Here’s how the typical Long Island household budget breaks down for major categories.

  • Housing: 38% ($28,040) compared to the U.S. average of 32.7%
  • Food: 13.3% ($5,352 at home, $4,491 away from home) compared to the U.S. average of 12.9%
  • Transportation: 12.5% ($9,255) compared to the U.S. average of 16.8%

It’s no surprise that the region’s high housing costs eat up a lot of the typical New Yorker’s budget. It’s also not shocking that New Yorker’s have lower transportation costs than average as it’s the only U.S. city where the majority of households don’t have a car, especially in Manhattan. However, Long Island is car-dependent with 75% of Long Islanders driving to work.

Suffolk County vs Nassau County Cost of Living

The best way to understand the average cost of living is to look at the cost of living index for Nassau and Suffolk counties and major areas in each. The Long Island cost of living index is higher in Nassau County or the south shore of Long Island than the east shore. The Nassau County cost of living index is 162, or 62% higher than the national average, compared to the Suffolk County cost of living index of 132.

What sets the two counties apart? Nassau County is more expensive due to higher transportation costs (67% above the national average) and higher housing costs. Nassau County has a housing index of 236 versus Suffolk County’s housing index of 178.

Long Island’s Nassau County is one of America’s most expensive counties and one of the most affluent.
