scatterplots for binary variables

[James Thompson]

Hi, I am very new to Stata so please forgive me if this is a very basic question.

I have a binary variable (Pen) that captures whether or not a person receives a pension and an age variable. I want to plot the proportion of pension recipients by age using a scatter plot. I have been struggling with it for a while. Any assistance would be really appreciated.

The mean of a 0/1 indicator is a proportion. A line graph may be a better way to show the trend if this is what you are after.

preserve
collapse Pen, by(age)
scatter Pen age, sort
restore

Thank you very much Andrew, this was extremely helpful.
The x-axis has an interval of 0, 50, 100. How would I change this so that it increases in intervals of 20 instead of 50?

[Andrew Musau]

scatter Pen age, sort xlab(0(20)100)

Thank you again
