Contexto:
Para determinar el marco muestral se utilizó la muestra por conglomerado denominado Probabilidad Proporcional de la Muestra (PPS), el cual permitió determinar el número de familias a estudiar por comunidad. Ésta se obtuvo calculando la población acumulada y la distribución de las familias tomando en cuenta el número inicial, que fue calculado aleatoriamente de un billete y de acuerdo al intervalo muestral.

Probability-proportional-to-size sampling[edit]
In some cases the sample designer has access to an "auxiliary variable" or "size measure", believed to be correlated to the variable of interest, for each element in the population. These data can be used to improve accuracy in sample design. One option is to use the auxiliary variable as a basis for stratification, as discussed above.
Another option is probability proportional to size ('PPS') sampling, in which the selection probability for each element is set to be proportional to its size measure, up to a maximum of 1. In a simple PPS design, these selection probabilities can then be used as the basis for Poisson sampling. However, this has the drawback of variable sample size, and different portions of the population may still be over- or under-represented due to chance variation in selections.

Note from asker:
| Justo lo que pensé tenía la duda porque inicialmente en mi busqueda en la web solo miraba size lo cual no coincide con muestra pero posteriormente y vi sampling. |
