ABSTRACT
Demolinguistic analyses can pursue very different objectives and therefore be located at a macro or micro level. In turn, the objectives established determine whether to proceed through qualitative or quantitative analysis, assessing the close and unavoidable implications that connect them. For quantitative analysis, it is essential to know the fundamentals of the statistics or tests that control it. These statistics affect the composition, distribution, and changes of populations, considered here as populations that know or use a specific linguistic repertoire. These statistics will put researchers in a position to approach making comparisons between populations, as well as projections into the future based on data from the present or from specific time series. Biases and errors are possible at all stages of analysis and must be avoided or justified as far as possible. Graphic representations are an essential component of demolinguistic research because they allow multiple or complex factors to be visualized in a simple way. To do so, demolinguistic research relies on the entire graphic catalog that is common in statistics and in demography itself. Given the link between languages and geography, cartography—more specifically, statistical cartography—becomes a fundamental instrument in analysis.
