[MATEI Alina Gabriela]

The Institute of Statistics, University of Neuchâtel is organizing on Wednesday, February 12, 2025 at 11:00 the seminar "Designing a national household sample survey for
assessing ICT access and use in Brazil" by Pedro Silva (SCIENCE, Brazil).

The seminar is hybrid (face-to-face and online).
See the room and link below.

Abstract:
Conducted annually since 2005, the NIC.br ICT Households Survey (ICTHS) aims to map ICT access and usage in urban and rural households in Brazil, covering individuals 10 years old or older. We have just completed redesigning the sample for this survey aiming for the 2025 survey round. The redesign was motivated by the need to incorporate the updated sampling frame provided by the Brazilian Population Census 2022. As part of the redesign, we used some optimization techniques to form Primary Sampling Units (PSUs) by combining Census Enumeration Areas (CEAs), the most detailed areas for which the Census provided some information. The design is a stratified three stage cluster sample, with PSUs stratified by geography and an indicator associated with socioeconomic level of the PSU population. Sampling of PSUs and of CEAs within PSUs that have three or more CEAs was carried out using Pareto PPS Sampling. Sampling of households within each PSU or CEA is by simple random sampling without replacement. I will highlight some challenges faced during the design and how they were overcome with some of the design solutions.
Joint work with Marcelo Pitta (NIC.br) and José André M. Brito (ENCE)
