Briefings on this survey

Based on comments from the interviewed people and the field work teams, there were a few important comments regarding the media in Guatemala. Some people did not know terms such as Blogs, I-tunes and Podcasts, but they used these services on the web. Others did not know these terms but they had used the internet to find information and entertainment  The selection of the interviewee was a complicated by the “last birthday” technique.  People were slightly distrustful of high insecurity levels among the country, mainly in the urban areas. People were slightly distrustful of interviewers and there was a general level of insecurity in revealing information to them.  This presented a problem in the data gathering, and increased the total number of contacts attempts.

 Sampling selection process and specifics

 The sampling selection was  selfweighting and a random selection was made in every stage. The sample just followed municipality and sex quotas (50% men and 50% women).

This is a simple explanation of the sample process:

  • In the first phase 14 municipalities were selected, according to the characteristic of the “Municipality with the highest  population in the country”
  •  In the second one the centers of localities.
  •  In third phase, blocks of dwellings and finally the private dwellings. In every house just one adult is selected. If there are several available adults in the house the one that celebrated his/her birthday most recently is chosen.

Number of adults in the survey’s defined target population and the percent of adult population included and excluded from the sample: Target population was defined between 18 and 60 years old. Population over 60 years old represents the 10% of the total population of 18+ at the 14 municipalities included on the study.
