Age is an interval level variable because it is measured on a continuous scale without a true zero point. While we can quantify differences in age (e.g. between someone who is 40 and someone who is 50, we can say that the latter is 10 years older), we cannot say that someone who is 0 years old has no age. Therefore, age is not a ratio level variable. Age is also not a nominal variable because it can be quantitatively measured and ordered, and it is not an ordinal variable because the differences between age categories are not necessarily equal.
