The article presents summaries of papers delivered at the 125th annual meeting of the American Statistical Association. The meeting took place on September 1965 in Philadelphia, Pennsylvania. In the paper "On the Construction of Stochastic Working Life Tables," by Haskel Benishay, stochastic working life tables are constructed and evaluated. The essence of the construction of stochastic rather than the traditionally deterministic working life tables is in the utilization of the realistic assumptions that the number of births, the number of entries into the labor force, the duration of life, and the duration of working life, are random variables. The end result is a working life table with a double entry in each cell rather than the single traditional one. The implications of this approach for the evaluation of fluctuations in various subcomponents of the labor force are evaluated. Another paper "Measuring Elasticities of Air Travel," by Samuel L. Brown, summarizes research on the response of demand for air travel to differences of fares, incomes, and elapsed travel time. There are three kinds of studies. Multiple regression studies of time series of air traffic, fares and income in the national domestic market yield short-period fare elasticities and income-elasticities. A quarterly first-difference model stands well the usual statistical tests.

The article summarizes the data regarding national conventions obtained from the questionnaires distributed to the delegates during the 1963 Council for Exceptional Children convention held in Philadelphia, Pennsylvania. The information is viewed as essential in future planning for these conventions. The summarized responses stated that national conventions should be held yearly and should continue to be scheduled as is the current practice. There should be a balance between speakers and the fields of interest should be adequately covered. There were also several recommendations made by the respondents stating to always have a panel, to confine research papers, to plan more demonstrations and others.
