free range statistics

Visualising income inequality social tables as a scatter plot rather than a dual axis bar/line plot. I use examples from eighteenth and nineteenth century France, England and Wales drawing on Branko Milanovic's Visions of Inequality 2023 publication.

Accessing data and drawing charts for nickel exports from New Caledonia, and world nickel prices, from 2008 to 2025.

Accessing data and drawing visualisations of net migration for Pacific island countries and territories.

Accessing population data for the Pacific and drawing two visual summaries of its recent and projected growth and absolute size, as used recently in a side event before the Pacific Heads of Planning and Statistics meeting in Wellington.

p-values under the null hypothesis do not necessarily have a uniform distribution.

Countries with higher income or consumption inequality tend to have more homicides per population. But looking at the relationship within each country's data, there does not seem to be a consistent relationship between inequality and homicide rates (that is, when there is a relationship in some countries, on average there is no evidence of such a relationship). This is an interesting multilevel or mixed-effects modelling problem that could easily trip one up.

I draw a map of the Pacific showing the key locations associated with the disappearance of Amelia Earhart and Fred Noonan in 1937.

A reflection on ten years, 225 posts and 350,000 words of the Free Range Statistics blog. Blogging works for me because it meets my own needs in the first instance, particularly by motivating learning and giving me a structured platform to engage with things I find interesting.

Motivated by an excellent recent book, I explore Papua New Guinea's statistics for GDP, population, employment and vaccination rates.

A few specific notes on technical issues relating to a previous post. On drawing network graphs with different coloured edges; modelling strategy; different specifications of models; and accessing UN SDG and gender inequality data.
