SMEs Internationally
SMEs generally account for 95% of enterprises and 60-70% of employment in most economies.
International comparisons of the contribution of SMEs are often difficult to make due to the different methods used to collect and communicate firm-level data by central statistical agencies. Tables 9 and 10 provide information on a limited number of countries where comparable and recent data was readily available.22
Countries also have different firm size classifications. For example, in the United States the definition of SMEs is industry specific, meaning that in some cases firms with up to 500 employees can be classified as small businesses.23 In the United Kingdom, an SME is generally considered to be a firm with less than 250 employees.24
The OECD generally defines SMEs as firms with fewer than 500 employees. Using this definition, SMEs internationally constitute around 99 percent of enterprises and account for 60 to 70 percent of employment.25
For all countries represented in these statistics, except New Zealand, the number of employees determines size class. For New Zealand, the number of FTEs determines size class and the 100-499 size class includes all businesses with 100 or more FTEs.

The structure of the New Zealand private business environment (shown in parentheses) is strikingly similar to that of Australia. A slightly smaller proportion of private businesses in Australia fall into the smallest size categories.
