ISO 31661- alpha-2 two-letter country codes (character).

firstTest

Date of first test of a nuclear weapon.

firstTestYr

lubridate::decimal_date(firstTest)

yearsSinceLastFirstTest

c(NA, diff(firstTestYr))

nuclearWeapons

number of nuclear weapons

nYieldNA, nLowYield, nMidYield, nHighYield

number of weapons for which the yield in (nYieldNA) = unknown or variable, (nLowYield) = at most 15 kt (kilotons), the size of the Hiroshima bomb, (nMidYield) = greater than 15 but less that 50 kt, and (nHighYield) = at least 50 kt.

popM, popYr

popM = estimated population in millions for year popYr, per the Wikipedia article for the indicated country on 2020-02-05.

GDP_B, GDPyr

GDP_B = nominal Gross Domestic Product in billions of US dollars for year GDPyr, per the Wikipedia article for the indicated country on 2020-02-05.

Maddison

Country code used by the Maddison Project.

startNucPgm

Estimated date of the substantive commitment of the country to obtain nuclear weapons. See 'Details' below

startNucPgmYr

lubridate::decimal_date(startNucPgm)

Details

Most of the contents of this dataset are easily defined and not controversial. That's not true for the date upon which each country started its nuclear program, coded in startNucPgm and startNucPgmYr. The following summarizes the rationale behind the selection of the date for each country in this dataset.
