Urban Population Density: A Comment [PDF]
Environment and Planning A: Economy and Space, 1981 The poor results obtained with certain members of the quadratic gamma family is shown to be due to a specification error in most of the members of that family. By choosing a more admissible travel-cost function, the displaced quadratic gamma function is derived, which does not contain this specification error.

Density-vague population change
Trends in Ecology & Evolution, 1986Explicit density-dependence differs from density-vagueness in the sort of regulation imposed on populations. Explicit density-dependence implies regulation toward a central equilibrium point, whereas density-vagueness implies population change away from the two extremes of extinction and immense densities.

Population Density and Group Size
American Journal of Sociology, 1972This study looks at the relationship between the size of the small interacting group (in numbers of persons) and its environment in this case, the density of its immediate population. We hypothesized that persons in more densely populated areas will gather for social interaction in smaller groups, in fewer bisexual groups.

Population Density and Infrastructure Development
Review of Development Economics, 1997A model is proposed with the following features: (1) there is a publicly accessible transport technology, which is more advanced when there is more specialized labor in it; (2) a high population density facilitates the development of the transport technology; (3) an improved transport technology facilitates a finer division of labor, which in turn ...

Population density estimation.
Progress in food & nutrition science, 1989In many modeling situations, a set of values for the model parameters is regarded as characterizing an individual. The modeler may, however, be interested in estimating the distribution of parameter values in the population from which the individuals are sampled.
