Consider a total dependency ratio (TDR) for a population in which we multiply the result by a constant of 100. If the value of the TDR is 105 this would mean: a. that there are 105 dependents per 100 producers in the population b. that there are 100 dependents per 105 producers in the population c. that there are 5 producers per 100 dependents in the population d. that there are 100 producers for every 5 dependents in the population e. that the distribution of dependents and producers in the population is balanced
