Aitchison and Carter’s analyses of the Census over the last decades have succeeded in making the main trends concerning the spatial distribution of Welsh known to everyone with an interest in the future of the language. Even so, some aspects remain unexamined. This paper is an attempt to give a different view of the trends by presenting a number of new analyses. In the first part, language production between 1991 and 2001 that is the effect of the education system, is examined. It is shown that the introduction of the National Curriculum in Gwent led to the biggest changes. In the second part, the geographical distribution of Welsh-speakers is looked at, especially those areas where more than 70% could speak Welsh. Some indices are introduced in order to quantify the situation and to explain the significance of those areas. Lastly, the implications of spatial distribution (or social network) to the use of Welsh is discussed by consideration of a little probability theory.
