Between 1960 and 2010, the average household size in Saint Lucia decreased from
4.22 persons to 2.81 persons. During that period, two parallel trends contributed
to the decline: a significant increase in the number of households and a drastic
growth in one–person households.
This paper traces the major trends in household formation since 1960 and develops
a set of nationally representative household projections that could help determine
future housing demand. It begins with an examination of the existing
extrapolative methodologies for developing household projections and provides an
outline of the household membership rate procedure as a suitable methodology for
deriving robust projections of future household numbers and the distribution of
households by size for Saint Lucia. Using census data from the last four decades,
household projections are then produced for the years 2015 to 2030 in five-year
intervals
