Philippines - Labor Turnover Survey 2011

The enterprise is the unit of enumeration in the LTS and it has for its sampling domain the fourteen (14) major industry groups (1-digit) based on the 1994 PSIC. The coverage of the survey was limited to large business enterprises in Metro Manila due to budget constraints and in line with the instruction of DOLE officials to conduct a quick/timely assessment of the labor market activity through a sample survey with manageable sample size. Metro Manila accounts for one-third of the country's gross domestic product and about two-thirds (64.5%) of the total large business enterprises in the Philippines.

The sampling frame was extracted from the Top 10,000 Corporations in the Philippines as compiled by the Securities and Exchange Commission (SEC). The frame contains the names of 3,064 enterprises in Metro Manila listed in order of their gross revenue/sales in 2011.

The sampling design is stratified random sampling wherein the 3,064 firms ranked according to revenue would be stratified into two. The first stratum would consist of the Top 200 firms and would be taken as certainty stratum which means that all of these 200 firms would be part of the sample. The second stratum would comprise the remaining 2,864 firms from which a random sample of 500 would be taken.

A total of 700 sample enterprises shall be taken.


Replacement of sample enterprise is done when the sampled enterprise falls in one of the following situation during the field operation: (1) cannot be located; (2) refuse to answer; (3) temporarily closed; (4) duplicate of another sample enterprise; (5) permanently closed; or (6) on strike.
