Declining enrollment is an issue that has plagued schools across America for the greater part of the last decade. While various factors are likely to be at fault, declining birth rates, especially in states that encompass portions of the nation’s largest metropolitan areas, are one large factor leading to the phenomenon. In New Jersey in particular, the count of live births dropped from 106,922 in 2010 to 97,954 in 2020, marking an 8.4% decrease in just ten years.[i] In roughly the same amount of time, the state’s population has increased 5.5%.[ii]  This puts New Jersey at the fourteenth lowest among states for live birth rates, according to the U.S. Census Bureau’s Population and Housing Unit Estimates Program.[iii]

Concurrently, enrollment in public schools has declined over the last ten years and is projected to decline at an even faster rate in the coming decade. According to the National Center for Education Statistics (NCES), New Jersey schools experienced a 2% decrease in enrollment from Fall 2010 to Fall 2021, and an additional 7% drop is projected to occur between Fall 2021 and Fall 2031.[iv] This could present a problem for New Jersey schools, given that funding for schools from both state and local sources is calculated on a per-pupil basis. In other words, the fewer the pupils enrolled, the fewer the dollars budgeted for teacher’s salaries, supplies, building overhead costs, and more.[v]

Figures 1 and 2 below present year-over-year changes in both K-12 public school enrollment and total population in the state, which clearly do not display a straight-line divergence for either measure. Particularly for the enrollment numbers, the effect of the COVID-19 pandemic, which hit during the latter half of the 2019-2020 academic year, is accentuated. In just one year, total enrollment in all New Jersey public schools dropped from 1,375,829 to 1,362,400 students. There are a number of possible motivating factors that may have led to parents withdrawing their children during this unprecedented time—concerns regarding pandemic restrictions and/or exposure to the virus, dissatisfaction with changes to curriculum, or other additional burdens placed on students whose parents had to continue working through the pandemic.

Interestingly, not all NJ schools saw drops in enrollment. In the Newark City School District (which is majority-minority in makeup and overwhelmingly low-income), enrollment grew by 4,000 students from 2019 to 2021.[vi] In the nearby (much smaller) South Orange-Maplewood district, this number conversely declined by 400 students.

The inconsistency between these two sampled districts corresponds to contrasting statewide enrollment changes between certain demographics during this same time range: “Including charter school enrollment, the number of White students in public schools statewide dropped by 39,000, and the number of Asian students fell by 2,400. Black enrollment climbed 900, and the number of Latino students grew by 20,100.”[vii]

While birthrates are likely to blame as aforementioned, so is economic mobility. Families in wealthier districts generally have greater access to private and other alternative education methods for their children as opposed to lower-income families who may not be able to afford private school tuition or to take time off work to homeschool, for example. To put this into perspective against the enrollment changes by race, data sourced from the March of Dimes Foundation reports that “of all live births in New Jersey during 2018-2020 (average), 69.9% were White, 16.8% were Black, 0.2% were American Indian/Alaska Native and 11.7% were Asian/Pacific Islander.”[x] This points again to the fact that while birthrates are indeed declining and contributing to the loss of students in New Jersey public schools as a whole, this may not be the case when performing a district-by-district analysis as most of the live birth population continues to be White (while they concurrently represent the largest demographic of public school enrollment loss). With less dollars spent in districts with higher rates of declining enrollment, it becomes less likely that fiscally able parents will be to send their children to underfunded schools—contributing even further to this disparity.

To understand these enrollment trends and their true fiscal impact on each New Jersey public school district, it is evident that research must delve into a more granular level, taking into account a greater multitude of demographic variables.
