4. Limitations
One of the major limitations of the study is the large concentration of participants in Colombo.
This has resulted in a disproportionate distribution of the sample among different geographical
areas in the country, but this situation could not be avoided due to the large concentration of
offices within the capital city, Colombo, as against other regions.
The other limitation was under representation of professionals in the sample compared to the
national distribution. This may have affected the results associated with the different age group
categories and the general national scenario, to a certain extent, but the results for each employment
group are unlikely to have been affected.
