Many characteristics of this dimension vary from one country to another, and it is this dimension that has undergone the greatest changes in measurement owing to spectacular advances in communications markets and their fast-expanding coverage. In many cases, differences from one year to another stem from the addition or removal of various household information or communication goods. This is the case with Honduras and the Plurinational State of Bolivia, where the changes stem not from the scale of deprivation but from differences in the way the dimension is estimated, and Argentina, where there is no possibility of measuring this dimension.
