3. 3 Indicators Births and Deaths –Thresholds - All enterprises -Employer enterprises (with turnover) -(Economic) Enterprises with 2+ employees (with turnover) Consistent treatment of real births vis-a- vis reactivations, mergers, take-overs etc

4. 4 Indicators Survival Rates –3 year survival and 5 year survival An enterprise born in year xx or having survived to year xx from a previous year is considered to have survived in year xx+1 if it is active in terms of turnover and/or employment in any part of year xx+1 (= survival without changes). Births and deaths follow the measures outlined earlier.

6. 6 Indicators High Growth –All enterprises with average annualised growth greater than 20% per annum, over a three year period, and with 10 or more employees in the beginning of the observation period, should be considered as high-growth enterprises: measured by the number of employees and by turnover. Gazelles –All enterprises up to 5 years old with average annualised growth greater than 20% per annum, over a three year period, and 10 or more employees in the beginning of the observation period, should be considered as gazelles.

7. 7 High-Growth Developments Composite Indicators –Paper develops hybrid Employment-Turnover based measure

8. 8 High Growth Developments Previous indicators require some convention: growth threshold, size-class cut-off to avoid small firm bias. What about Birch–type Indices to overcome size-class bias? combined with convention that we take the top X% of enterprises in any country as high-growth.
