In this paper, I begin with a brief sketch of the history of human eco
logy. I then point out that its problems are more complex than those o
f general ecology and review some basic features. A discussion of how
the demography of households can be approached from an ecological pers
pective follows, then I outline ways to improve the formal and methodo
logical aspects of human ecology. To conclude the paper, I argue that
demographers could gain by thinking in human-ecological terms.
