Philippines - Labor Turnover Survey 2014

The enterprise is the unit of enumeration in the LTS and it has for its sampling domain the eighteen (18) major industry groups (1-digit) based on the 2009 PSIC. The coverage of the survey was limited to business enterprises in Metro Manila due to budget constraints and in line with the instruction of PSA 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 of the total large business enterprises in the Philippines.

The sampling frame for the 2014 LTS is an integrated list of enterprises culled from the 2013 List of Enterprises in the NCR prepared by the Philippine Statistics Authority (PSA) and the updated sampling frames of 2012 LTS and 2013 LTS. This comprises 19,628 business firms/enterprises with an employment size of at least 20. This list is obtained on the first quarter of the year. The sample size will be computed based on this frame on the first quarter. The same sample size will be used until the fourth quarter.

After each survey round, all enterprises that responded are automatically considered as samples for the next survey round. To fill up the lack in the computed sample size, samples will be drawn by industry from the updated sampling frame. In cases where there are no enterprises to sample in some industries, the total number of samples needed for these industries will be allocated proportionally to other industries with available samples.

The sample enterprises in each domain were drawn through simple random sampling.


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.





Weights were not computed.
