A measure of concentration of the use of time, with an application to the pattern of daily leisure activities

“…A time-use profile heavily concentrated on a few activities would be typically classified as little diversified and varied, or as very specialized. Hufnagel (2008) deals with the evaluation of time-use diversity across consecutive days, what requires at least two activity profiles. Variety, understood as the number of different activities undertaken (Gronau and Hamermesh, 2008;Ray, 1979;Sonnentag, 2001), ignores how time is distributed across activities engaged in.…”
