Manufacturing employment in Mexico grew in March (0.3%), after 18 months of year-on-year falls, Inegi reported.
At a month-on-month rate, manufacturing employment grew 0.4%, accumulating 10 months of consecutive advances.
These results originate from the Monthly Survey of the Manufacturing Industry.
At an annual rate, hours worked were higher by 1.9% and real average wages rose 3.3% in March.
By eliminating the seasonal factor, the real average wages paid in the manufacturing sector increased 0.8% in the third month of the current year compared to the previous month.
Disaggregated, salaries paid to workers increased 2.3% and social benefits 0.3%, while salaries paid to employees decreased 0.1% at a monthly rate.
The observation unit of the survey is the manufacturing establishment, which is defined as the economic unit that, in a single location, delimited by constructions and fixed installations, combines resources under a single owner or control to develop on its own or third-party account (maquila ) activities of assembly, processing and total or partial transformation of raw materials that result in the production of goods and related services, mainly comprised in a single class of economic activity.
The EMIM includes establishments that produce goods, as well as those that have the Manufacturing Industry, Maquiladora and Export Services Program (IMMEX).
Likewise, the coverage of the manufacturing employment survey allows estimates to be obtained at the national level, by type of activity, branch, subsector and sector of the 2013 North American Industrial Classification System (NAICS).
Of the 239 classes of economic activity considered in the survey, 235 have a non-probabilistic design and the remaining four classes have a probabilistic design.
The establishments of the classes with non-probabilistic design were selected according to their greater contribution in the variable of total income.
The sample size was obtained by accumulating as many economic units until reaching the established coverage.
In addition, the establishments of the classes with probabilistic design were selected randomly and independently, as selection variables the total employed personnel and total income were taken.
To conclude, in these classes the sample size was obtained independently through the expression to estimate a total, with a confidence level of 95%, a relative error of 10% and an expected non-response rate of 15 per cent. hundred. Stratum 1 is considered with certainty.
