The paper presents a model for teaching demography used at the University of Waterloo which requires student projects. Three projects are described in some detail. They are analyses of unemployment rates. future housing requirements in the Province of Ontario, and the need to modify the normal retirement age of 65 used in the Canada/Quebec Pension Plan. Keywords: Canadian baby room, Labour force tion. Unemployment, Housing; Social security; Quebec pension plan; Normal retirement Age.

increase the effectiveness of the course I decided to assign each student a major project that was an applied demographic problem. This experiment has turned out to be extremely successful. In the first two weeks of the thirteen week term, each student meets with me to have their project summary approved. The summary consists of a short outline of the topic and the student’s ‘plan of attack’. At this time, I acquaint the student with the existing literature pertinent to the topic (see references). The projects are due the last day of class and are worth 20% of their final mark. The project must be presented in a format appropriate for a senior essay. While length is not the prime concern, these projects are usually twenty to thirty pages long including supporting data, computer programmes, etc. To complete such a project, students need to 0167-6687/84/$3.00

Barnard had assumed a constant fertility rate of 2.105 and net immigration of 50000 per annum. But during the 1970’s, fertility rates in Ontario had continued to decline and by 1981 seemed to be stabilizing at around 1.800. It should be noted, however, that the fertility rate assumed is not very important in estimating total households to 2001, because those born in 1976 will only be 25 years old in 2001.

which commence at age 65, are indexed to the Consumer Price Index. The contribution rate of 3.6% in total was set at a level that would generate a fund in the early years of the plan when many workers contributed but few received benefits. These funds were lent to the provinces. The provinces are expected to pay interest on the debt and repay the debt itself when the cash flow becomes negative (expected in early 1984). When the 3.6% contribution rate was estab-

lished in 1966, it was anticipated that it would remain at that level and then rise slowly to an ultimate level as the plan matured. At that time the cost estimates did not anticipate the baby boom/bust cycle. It is difficult to believe that the next generation of workers will be willing to fund the C/QPP given the contribution rates now being projected. The report of the Royal Commission on the Status of Pensions in Ontario (Haley, 1981) included the following comments: “On a pay-as-you-go basis. where benefits are paid as they fall due without any assets being accumulated, the 3.6% contribution rate covers the benefit payments until after 1985. The cost would rise steadily thereafter to a peak of 9.28% in 2030. With full funding (i.e. level premium funding with unfunded liabilities at 1980 amortized over 50 years) the contribution rates would be required to increase to 12.53% in 1980. The fund would increase from $25 billion in 1980 to $712 billion in 200 and $8.86 trillion in 2030”.
The commission recommended that the Canada Pension Plan should be funded on a pay-as-you-go basis with a contingency fund maintained at the level required to satisfy twice the year’s benefit and administration cost pay-out three years in advance. The solution that has been adopted in the U.S. with respect to a similar funding problem has been to raise the normal retirement age from 65 in 2003 until it is 67 by 2027. In this project we attempted to find a shift in the normal retirement age in Canada that would avoid the sharp rise in the aged dependency ratios outlined in Table 1. As the basis of our analysis, we used a Statistics Canada population projection that assumed net immigration of 75000 per annum, mortality that decreases slightly to 1986 and remains level thereafter, and fertility that declines to a level of 1.7 in 1991 and remains constant thereafter. Based on that population projection and a large number of retirement formulae, we chose a model whereby the eligibility age for social security benefits (now 65) would rise by three months each year starting in 2008 until it reached age 70 in 2027. The effect on dependency ratios can be seen in Figure 6. Because the dependency ratio remains fairly level from 1999 to 2007, we decided that 2008 was the best point to start the retirement age change. It would be difficult to postpone it beyond 2008.

Fig. 6. Retired population per 100 workers aged 20-64. (I) if retirement age remains at 65; (II) if retirement age is raised according to the model.
As can be seen from Figure 6, there are presently more than six workers per aged dependent. If no change is made in the normal retirement age, that ratio will go to three workers per retired dependent as anticipated in Table 1. With our proposed formula, however, the ratio would never reach five workers per retiree and, hence, the C/QPP contribution rate would not have to rise to 9.28% as projected by the Haley Commission. Further, if today’s rate of mortality improvement continues, Canadians could spend as much time in retirement under the new formula as they expect to today.
