The SIA also includes periodic quarterly surveys, as part of the institution's 2018-2022 activity plan, according to Patrick Pedro, senior technician at INE Angola.
The process of collection, processing and dissemination of the SIA were presented during a methodological seminar promoted by INE.
According to Patrick Pedro, the sample for the SIA selects 10,944 households quarterly in the country's 18 provinces and for the labor market statistics the reference period is seven days prior to the survey.
At least 115 INE agents, namely 95 field agents, including three surveyors for each of the 17 provinces and six for Luanda, and 20 technicians, work directly in the preparation of the SIA, described in a Quick Information Sheet (FIR).
For the SIA calculation methodology, he explained, the eligible population is the economically active (sum of jobs and unemployed) and the inactive population in the reference period.
"The concepts, which we apply, result from the recommendations of the International Labor Organization (ILO), thus making them universal," noted Patrick Pedro.
The refusal by households to provide information to the inquirers, the absence of households at the time of the interview, areas of difficult access and lack of publicity about the SIA were pointed out by the responsible as some of the constraints in the preparation of the survey.
The unemployment rate in Angola rose to 31.6 percent in the second quarter of 2021, up 1.1 percent from the previous quarter, and the employment rate in that period fell 1 percent, INE said on Friday.
Employment in the second quarter of 2021 fell by 1 percent from the previous quarter and was up 6.4 percent from the same quarter in 2020.
The indicators on the SIA for the second quarter of 2021 were presented by the head of INE's Demographic and Social Statistics department, Teresa Spínola.
