5. Project Background

6. A Census-Based Proxy for Student Socioeconomic Status and Income Based on census data for income, education (BA or higher) and occupation (professional/managerial) Student address matched to census Student assigned median household income and SES for area mapped

7. Washington State Socioeconomic Status Quintiles 1990 and 2000 Washington State SES 1990 Household Income ($1999) Adults with BA degree or higher Persons employed professional % Total State Population Highest $61,61545%44%20% Higher $46,58126%31%23% Middle $39,86518%24%22% Lower $34,08812%18%19% Lowest $24,4447%12%17% Washington State SES 2000 Household Income ($1999) Adults with BA degree or higher Persons employed professional % Total State Population Highest $74,70754%55%19% Higher $55,62534%40%20% Middle $47,43723%33%20% Lower $39,92516%26%21% Lowest $29,51510%18%20%

8. Race still matters

9. State population- more than ever before our future adults are being born and raised in low SES households.

10. Participation rates measure how close the resemblance is between state population and CTC students Part Rate = % of students ÷ % state population Part Rate less than 1 = less than population Part Rate 1 = Parity Part Rate greater than 1 = more than population

11. Participation for Younger and Older Students by SES Quintiles - 2000 LowestLowerMiddleHigherHighest CTC Students (18-24 Yrs).8.861.051.141.35 CTC Students (25 +) 1.211.05.99.96.75

12. Students socioeconomic differences become even more magnified by colleges, raising the question: “How best can the system support colleges so varied in student body and community make-up?”

14. Data Structure

15. Relational Database (MS Access) SBCTC Data Warehouse (student data) Census Data Tables (population data) Spatial Data GIS

16. GIS – Quick Intro GIS = Geographic Information System Useful for: Visualizing distribution Spatial analysis Types of Data: 1. Point (students @ home addresses) 2. Line (roads, rivers) 3. Polygon (block groups, lakes, cities) 4. Raster (hillshade, aerial photo)

20. Spatial Data – Raster

21. Database – Examples of Variables DW – Student Data Family status Fund source Ed background Ethnicity Program Intent Census – Population Data Demographic Ed background Ethnicity SES Median household income/ethnicity Employment

22. Database – Placing Students in Block Groups GIS BG# 530730009003 DW Address: 234 Main St, Bellingham 98225 Student on Map BG # on Student Record

23. Database – Adding Student Data to Block Groups BG# 530730009003 Student data is aggregated for each block group and can be joined to the block group data by block group number BG# 530730009003 Students: 218 % Hispanic Students: 5.4% # Transfer Students: 59

24. Applications: SES of Students attending Washington State Community & Technical Colleges

27. Applications: Demographics of Students attending Skagit Valley College

28. 1. Where do our students come from? 2. How has the SES of our district changed between census dates?

31. Applications: Serving our Minority Population

32. 1. What is the median household income of Hispanic students in our district? 2. Where are minority groups concentrated within our district? 3. Should we extend our ESL program to a remote location?

34. Hispanic SVC Students' Household Income N1,414 Mean$31,782 Median$31,500 Std. Deviation$18,196 Quartiles25%$27,012 50%$31,500 75%$37,273 Based on Median Household Income Census data for the Hispanic population of the block group.

37. Applications: Improving our Enrollment/Marketing Efforts

38. 1.What percent of the population is between 18 and 25 years of age? 2. What is the geographic distribution of the population older than 25 years who have less than an Associate’s Degree? 3. What percent of the district population attends a community or technical college?
