The study examined the labor force participation of Ontario secondary school students during the summer of 1973. A sample of schools stratified by region, size of community, and school type was taken. Within each school in the sample, students in levels 2, 3, 4, and 5 completed questionnaires. The tables presented in the report are based on the distribution obtained from the sample survey. Job search methods, rates of success in finding employment, and the characteristics of that employment were investigated. Comparisons were made with data gathered in a similar survey undertaken in 1969. The results indicated that 78% had either worked or looked for work during the summer of 1973, with the rate increasing with age. In all groups males had higher participation rates than females. Other factors influencing labor force participation were community size and geographic location. The job seeking method most frequently used was direct application, followed closely by family or personal contacts. Overall, 85% who sought jobs were successful. The largest summer employment of high school students in 1973 was the service industry, with trade and primary industries running second and third. Fifty percent of employed students earned an hourly wage of $2.00 or less. The median wage was $1.85 per hour for females and $2.16 for males. The survey instrument is appended. (NJ)
