The Compendium of practices on the implementation of information and communication technologies (ICT); questions in households and businesses surveys has been prepared by the Observatory for the Information Society in Latin America and the Caribbean (OSILAC);, in cooperation with the working group on ICT measurement of the Statistical Conference of the Americas of ECLAC with the following objectives: i); to collect and organize the main developments in the design and implementation of questions on access and use of ICT in the household and business surveys of the countries of the region, ii); to report the measurement agreements by the countries of the regions that have collected data on ICT in the framework of their household and business surveys, iii); to serve as a reference, or support material, both to the persons responsible for the design and implementation of the ICT questions, and to the persons in charge of defining, calculating and analyzing the ICT indicators, in the countries of the region, iv); to enable the exchange of implementation experiences among the organizations and institutions that produce statistical data on ICT in the countries of the regions.There are two main novelties in the Compendium revision 2010 in relation to the previous Compendium (2007);: first, the increase in the number of countries for which we present the main characteristics of the implementation of ICT questions and, second, the inclusion of two new chapters concerning subjects of ICT measurement in the education sector and in the government.The cases included correspond to the countries that have incorporated all or part of the ICT questions and core ICT indicators' list recommended by the Partnership on Measuring ICT for Development (2010);. We emphasize the cases where the countries of the region incorporated both the ICT access variables and the ICT use variables in the household and business surveys of the last three years and whose data was not included in the previous Compendium.
