Note that a parameter is a numerical value that describes a population, for example, the population mean, the population proportion, the population standard deviation e.t.c normally every participant is involved in the calculation of the parameter. On the other hand, a statistic is a numerical value describing the characteristics of a sample data.  A statistic is used to estimate a parameter. 

The case above is a parameter because all the respondents were members of the population.
