Determinants of the number of heavy metal musicians per capita

Abstract

This study is a follow-up to the 2015 study titled ‘Determinants of the production of heavy metal music’. That study attempted to find an equation that would predict the number of heavy metal bands that each country had. That study was unable to arrive at a single equation, and double counting the output of musicians who were in more than one band was likely the reason. This study re-tests the variables that were found to be significant in the original study, some alternatives to those variables, and reconsiders some variables that were not found to be significant in the original study. To overcome the problem that the original study had with double counting the output of musicians who were in more than one band, this study uses the number of metal musicians per 100,000 people as the dependent variable rather than the number of heavy metal bands per 100,000 people. The independent variables considered in this study are as follows: the percentage of population with access to electricity, the number of unpaid parking tickets per UN diplomat during the period in which the City of New York was not enforcing parking violations on diplomats, the number of concert halls per million population, the Democracy Index, the percentage of the population who speak English, per capita electrical consumption, the average GDP per capita for the prior 3 years, the GINI index, latitude, life expectancy, Scandinavian Law, the average number of years of school that a citizen is expected to complete, the number of years the country was governed under constitutions that made reference to Marxism (with several variants capping the number of years at 20, 30, 40, 50 and 60), males between the ages of 15 and 24 as a percentage of the total population, males between the ages of 15 and 24 as a percentage of all males, the percentage of the population that identifies as Catholic and the percentage of the population that is not affiliated with a religion. The study found that changing the dependent variable from the number of metal bands per 100,000 to the number of metal musicians per 100,000 people did address the problem of double counting the output of some musicians; the original study was unable to arrive at a single equation as a model, this study was able to do that. This study and the original study arrived at the same significant independent variables: the number of concert halls per million population, latitude, Scandinavian law, Years Marxist, males between the ages of 15 and 24 as a percentage of the total population, the percentage of the population that identifies as Catholic and the percentage of the population that is not affiliated with a religion.
