SMEs Internationally
SMEs generally account for more than 95 percent of enterprises and 60-70 percent of employment in OECD economies.
There is no universal definition of a SME, although there has been a push for countries to adopt similar definitions to enhance comparability.16 International comparisons of the SME economic contribution are often difficult to make because of the different methods central statistical agencies use to collect and communicate firm-level data. However, even taking into account the variation in definition, the OECD recognises that SMEs make up over 95 percent of firms and 60-70 percent of employment, and that they generate a large share of new jobs in OECD economies.17
Most countries use an employment measure to define SMEs. The following are examples of international SME definitions in numbers of employees:
| | Micro | Small | Medium | Large |
|---|
| European Commission18 | < 10 | < 50 | < 250 | - |
|---|
| United Kingdom19 | < 10 | < 50 | < 250 | 250+ |
|---|
| Australia20 | < 5 | 5-19 | 20-200 | 200+ |

A large number of firms in all countries, including New Zealand, fall into a "micro" category. At February 2004, a micro firm category would capture most enterprises in New Zealand (92% using the EC/UK definition, 86.8% using the Australian definition). Allowing for differences in data collection and methodology, New Zealand has a similar proportion of small firms in the economy to other OECD countries.21
Tables 10 and 11 provide information on a limited number of countries where comparable and recent data were readily available.
