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

  1. 1. Investigating Missouri Per Pupil Expenditure as a Function of Median Household Income Adam Geller University of Missouri – St. Louis
  2. 2. Two Main Data Sets <ul><li>Median Household Income </li></ul><ul><ul><li>United States Census 2000 </li></ul></ul><ul><li>Per Pupil Expenditure </li></ul><ul><ul><li>Missouri Department of Elementary and Secondary Education </li></ul></ul>
  3. 3. <ul><li>Wealth concentrated in urban areas </li></ul>2000 Median Household Income
  4. 4. <ul><li>Spending has no clear pattern </li></ul><ul><li>Pockets of high spending in low income areas as well as in high income areas </li></ul>2007 Per Pupil Expenditure
  5. 5. Full Data Set
  6. 6. Full Data Set <ul><li>R 2 = 0.00127 </li></ul><ul><li>On the whole, median income does not serve as a predictor of PPE </li></ul>
  7. 7. Urban or Rural? <ul><li>All school districts geographically touching an urban census area were selected, in entirety, as urban districts. </li></ul><ul><li>This groups the metropolitan area as urban rather than only districts of cities proper </li></ul>
  8. 8. <ul><li>Map uses same color brackets as previous state-wide map. </li></ul><ul><li>Clearer concentration of wealth with mix of lower income areas </li></ul>Median Income of Urban Districts
  9. 9. Urban Districts PPE
  10. 10. Urban Districts PPE <ul><li>R 2 = 0.0701 </li></ul><ul><li>In urban districts, median income does not serve as a predictor of PPE </li></ul>
  11. 11. Rural Districts PPE
  12. 12. Rural Districts PPE <ul><li>R 2 = 0.0131 </li></ul><ul><li>In rural districts, income does not serve as a predictor of PPE </li></ul>
  13. 13. Median Income Brackets <ul><li>Missouri median household income was $43,266 </li></ul><ul><li>566 districts in data set </li></ul><ul><ul><li>139 districts above median income </li></ul></ul><ul><ul><li>427 districts at or below median income </li></ul></ul>
  14. 14. Median Income ≤ $43,266
  15. 15. Median Income ≤ $43,266 <ul><li>R 2 = 0.0027 </li></ul><ul><li>When median income is less than $43,266, PPE is not correlated to median income </li></ul>
  16. 16. Median Income > $43,266 R 2 = 0.1940
  17. 17. Very Top End May Skew The Relationship <ul><li>“ Clustering” begins below median income of these five districts </li></ul>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
  18. 18. $43,266 > Median Income < $75,000 R 2 = 0.0399
  19. 19. What does this mean? <ul><li>From this analysis, it is not clear whether any of these results are a “statistically significant” relationship </li></ul><ul><li>A multi-variable relationship is more likely to explain how PPE is affected </li></ul><ul><ul><li>Free and reduced lunch population </li></ul></ul><ul><ul><li>Special education population </li></ul></ul><ul><ul><li>Limited English proficiency population </li></ul></ul>
