The correct answer is Both 1 and 2.A population pyramidIt is also known as an age structure diagram, which shows the distribution of various age groups in a population.A common distribution often used with this type of visualization is female and male populations by age.To create a population pyramid using Tableau, first separate the population (measure) into two groups, females and males, and then create "bins" for the age cohorts you want to represent in the population pyramid. Hence, Option 3 is correct.A population pyramid is a graphical representation of the age and sex composition of a specific population.It consists of two histograms, one for each gender (by convention, men on the left and women on the right) where the numbers are shown horizontally and the ages vertically.The numbers by gender and by age depend on interactions between fertility, mortality, and migrations.The shape of the pyramid and its variations over the years depends, above all, on the variations in fertility.The pyramid can also assume a columnar shape (with vertical sides rather than sloped sides), or have an irregular profile.Indias pyramid is bottom-heavy i.e. the Indian population has a larger proportion of children, teenagers, and young adults compared to Chinas.
