N 14960.4 Population Data at a Glance Vaupel, J. W., Wang, Z., Andreev, K. F., Yashin, A. I. Odense Monographs on Population Aging 4. 98 pages. Odense, Odense University Press (1997). 16x25cm. "This monograph presents a bouquet of shaded contour maps to suggest the broad potential of their use in population studies. The value of such maps lies in their substantive import.... Demographic surfaces can be particularly complex. A mortality surface, for example, might be defined over a century of age and a century of time, comprising 10,000 data points that may vary over four orders of magnitude. Shaded contour maps are an arresting, efficient, and clear means of giving demographers visual access to such data." (EXCERPT) NOVO.
