#### How to create a new variable from census data in Stata?

We use variables of the census.dta data come with Stata as examples. Here we use the -generate- command to create a new variable representing population younger than 18 years old.

#### How to create a population younger than 18 years old using Stata?

We use variables of the census.dta data come with Stata as examples. Here we use the -generate- command to create a new variable representing population younger than 18 years old. We do so by summing up the two existing variables: poplt5 (population < 5 years old) and pop5_17 (population of 5 to 17 years old).

**What does Recode do to value labels?**

The recode command is most often used to transform categorical variables, which are many times value labeled. When a value-labeled variable is overwritten by recode, it may well be that the value label is no longer appropriate. Consequently, output that is labeled using these value labels may be misleading or wrong.
