  • Choose a Year — Select the year you are researching. Initially, the New Jersey Data Book will include data from 2010 through 2014. Data from previous years are being added within the next year.
  • You can also do a similar search by Legislative or Congressional district. Just choose the appropriate tab when beginning your search.
  • This easy process works for multiple data sets in a search or just one.


  • After you’ve selected the data you want, scroll down and click the Search button.
  • Your results will appear as a table.

Print or Download:

  • At the top of your results page, you will have the option to print or download the table.
  • If you choose “download,” a dialog box will ask you if you want to open the file in Microsoft Excel. Click “yes.”  Please note: Safari browser users will receive special instructions on downloading after selecting an excel file.
  • A Microsoft Excel spreadsheet will appear. Your data will be alphabetized by town and listed by year but you may save the table and reorganize the data as needed. You may save this file to your own computer.
  • If using  this data in a report or paper, please cite the New Jersey Data Book as your source

Sample Search:

You want to identify the five largest municipalities in Mercer, Middlesex and Monmouth counties using the most recent U.S. Census data.

  • Select the County tab.
  • Choose the counties you are interested in by clicking the boxes beside their names. A list of towns in each county will appear.  All will be checked. Since you are trying to identify which towns are the largest, leave all of the boxes checked. If you are searching for specific towns, uncheck the boxes of those you do not want to include.
  • Once you’ve selected those counties and their municipalities go to the next step.
  • Select Indicator.
  • In this search, you would click on the “population” indicator.
  • Several variables within this indicator will appear. You may select one or more of the choices by clicking inside the boxes next to them. Choose “Census Population” to get the official population for each municipality in those counties.
  • Choose a year, or multiple years: For example, you may select 2014 to view corresponding data for that individual year. Alternatively, you may select 1999 and 2014 to view and compare data corresponding to both of those years, all on one page. (We recommend selecting up to five years at a time for the best display performance).
  • Scroll down and click the “search” button.
  • A spreadsheet will appear with the U.S. Census populations for all the towns in those three counties. It will be alphabetized by town.
  • You can now either print the spreadsheet you see on your screen or download it as an Excel file. If you choose to download a spreadsheet, you’ll be able to organize it any way you want – numerically or alphabetically.  If you use your results in a paper or report, we request that you cite the Rutgers New Jersey Data Book as your source.
