Figure 1. Share of firms by size classes, 1963-1992
Due to data constraints, when the figures for 1970 and 1980 are disregarded, it can be said
that as a result of a steady increase in the share of micro firms from 0% in 1963 to 95% in
1992, that of other size classes has decreased. When the number of persons engaged has
been viewed by size classes, the rates are much more fluctuated as shown in figure 3. The
most important result from these two figures is that, the share of firms and the share of
persons engaged are not relatively distributed across the size classes.
