Investigating Missouri Per Pupil Expenditure as a Function of Median Household Income Investigating Missouri Per Pupil Expenditure as a Function of Median Household Income Presentation Transcript

  • Investigating Missouri Per Pupil Expenditure as a Function of Median Household Income Adam Geller University of Missouri – St. Louis
  • Two Main Data Sets
    • Median Household Income
      • United States Census 2000
    • Per Pupil Expenditure
      • Missouri Department of Elementary and Secondary Education
    • Wealth concentrated in urban areas
    2000 Median Household Income
    • Spending has no clear pattern
    • Pockets of high spending in low income areas as well as in high income areas
    2007 Per Pupil Expenditure
  • Full Data Set
  • Full Data Set
    • R 2 = 0.00127
    • On the whole, median income does not serve as a predictor of PPE
  • Urban or Rural?
    • All school districts geographically touching an urban census area were selected, in entirety, as urban districts.
    • This groups the metropolitan area as urban rather than only districts of cities proper
    • Map uses same color brackets as previous state-wide map.
    • Clearer concentration of wealth with mix of lower income areas
    Median Income of Urban Districts
  • Urban Districts PPE
  • Urban Districts PPE
    • R 2 = 0.0701
    • In urban districts, median income does not serve as a predictor of PPE
  • Rural Districts PPE
  • Rural Districts PPE
    • R 2 = 0.0131
    • In rural districts, income does not serve as a predictor of PPE
  • Median Income Brackets
    • Missouri median household income was $43,266
    • 566 districts in data set
      • 139 districts above median income
      • 427 districts at or below median income
  • Median Income ≤ $43,266
  • Median Income ≤ $43,266
    • R 2 = 0.0027
    • When median income is less than $43,266, PPE is not correlated to median income
  • Median Income > $43,266 R 2 = 0.1940
  • Very Top End May Skew The Relationship
    • “ Clustering” begins below median income of these five districts
    PPE Median Income District Name $10,134 $79,257 KIRKWOOD $9,262 $84,437 PARKWAY $7,676 $87,537 ROCKWOOD $15,248 $101,410 CLAYTON $11,984 $109,160 LADUE
  • $43,266 > Median Income < $75,000 R 2 = 0.0399
  • What does this mean?
    • From this analysis, it is not clear whether any of these results are a “statistically significant” relationship
    • A multi-variable relationship is more likely to explain how PPE is affected
      • Free and reduced lunch population
      • Special education population
      • Limited English proficiency population
