2 Overview KFS Background Sample Design Non-Response Status Summary KFS Background Sample Design Non-Response Status Summary

3 Kauffman Firm Survey Longitudinal survey of new firms Study dynamics and sustainability of new firms Sponsored by Ewing Marion Kauffman Foundation Dun & Bradstreet as the sampling frame Longitudinal survey of new firms Study dynamics and sustainability of new firms Sponsored by Ewing Marion Kauffman Foundation Dun & Bradstreet as the sampling frame

4 Kauffman Firm Survey (Cont.) Pilot study (new firms founded in 2003) Main study (new firms founded in 2004) Baseline survey (5000 firms & weighting) First follow up (4000 firms) Second follow up (expect 3500 firms) Pilot study (new firms founded in 2003) Main study (new firms founded in 2004) Baseline survey (5000 firms & weighting) First follow up (4000 firms) Second follow up (expect 3500 firms)

5 Sample Design Stratified random sample Strata High tech industries (3 levels) Woman-owned indicator Over sampling for high tech firms Stratified random sample Strata High tech industries (3 levels) Woman-owned indicator Over sampling for high tech firms

6 High Tech Firms BLS definition based on D&B employment Used SIC rather than NAICS Three categories High Tech Medium Tech Non Tech BLS definition based on D&B employment Used SIC rather than NAICS Three categories High Tech Medium Tech Non Tech

7 Woman Owned Firms Woman owned indicator composite D&B Indicator CEOs gender / prefix Final indicator results Tested in the pilot study Added 20% using CEOs gender Woman owned indicator composite D&B Indicator CEOs gender / prefix Final indicator results Tested in the pilot study Added 20% using CEOs gender
