Description

Average male heights in 144 countries from 1810-1989, with a smaller number of countries from 1500-1800. Data has been filtered to only include countries with more than one observation.

Usage

heights

Format

An object of class tbl_ts (inherits from tbl_df, tbl, data.frame) with 1490 rows and 4 columns.

Details

heights is stored as a time series tsibble object. It contains the variables:

• country: The Country. This forms the identifying key.

• year: Year. This forms the time index.

• height_cm: Average male height in centimeters.

• continent: continent extracted from country name using countrycode package (https://joss.theoj.org/papers/10.21105/joss.00848).

For more information, see the article: "Why are you tall while others are short? Agricultural production and other proximate determinants of global heights", Joerg Baten and Matthias Blum, European Review of Economic History 18 (2014), 144–165.
