RESULTS
Figure 7: Comparison of Academic Performance per schools
Suburban Growth and Public Expenditure Variation •! Enrollment and per
capita spending grew in every sampled district.*
•! The range in per pupil district spending rose by $199.55 between 2000 and 2014.
Public Spending and Academic Performance •! OPS had highest
return from increased spending.*
•! Westside had a drop in graduation rates despite increased spending.
Urban Sprawl, Public Expenditure, and Their Effects on High School Academic Performance in Omaha, Nebraska
José Lemus, Salfo Bikienga, and Dr. Hendrik Van Den Berg Department of Economics, University of Nebraska–Lincoln
Discussion •! Majority of Omaha’s urban sprawl occurred prior to 2000. •! We still see a medium level of urban sprawl within the city. •! Suburban districts have higher graduation rates than does OPS,
despite spending less per capita. •! Is there a statistically significant relationship between public
spending and academic performance?*
Future Work •! Understand the impact of graduation levels on ZCTA income
levels. •! Research the economic contributions of recent graduates on
the local economy. •! Investigate high school graduate preparation for post-
secondary education completion.

Introduction •! Urban sprawl significance in US. •! “Average high school graduation rate in the nation’s 50 largest
cities was 53%, compared with 71% in the Suburbs” (New York Times, 2009).
•! Current literature establishes positive relationships between secondary education public investment and economic growth (Jackson et al., 2015).
•! Investigating secondary-level human capital investment within Omaha, Nebraska, allows researchers to examine education provision patterns at an initial stage.
Purpose
1.! Understand the effects of public expenditure in secondary education on academic performance.
2.! Examine the role of suburbanization within the education provision of a mid-range city.
3.! Develop effective public policy to counter the suburbanization issues within growing metropolitan areas.
Hypotheses
1.! Consistent population migration to western edges of Omaha 2.! Significant public expenditure growth at the local level. 3.! Statistically significant academic improvement in lower
income schools.
