Global human population, 1700-2022. On 15 November 2022, the world’s population was estimated to reach 8 billion people, having grown by 1 billion since 2010. This is a remarkable milestone given that the human population numbered under 1 billion for millennia until around 1800, and that it took more than 100 years to grow from 1 to 2 billion. By comparison, the increase of the world’s population over the last century has been quite rapid. Despite a gradual slowing in the pace of growth, the global population is projected to surpass 9 billion around 2037 and 10 billion around 2058. Graphic: UN DESA

Evolution of democracy by category, 2008-2021. The EIU Democracy Index score ranges from 0 to 10, with 10 being best. this chart shows what has happened to the average global score across the five categories of the index between 2008 — before the global financial crisis — and 2021. The categories that have recorded the biggest deterioration in global terms are civil liberties (-1.00 on a 0-10 scale) and electoral process and pluralism (-0.47). Suggesting a possible correlation, functioning of government and political culture both recorded a very similar decline in their average global scores (-0.38 and -0.37 respectively). Graphic: EIU

EIU Democracy Index reached all-time low in 2021 – Fewer than half (45.7 percent) of the world’s people now live in a democracy of some sort – “Another bad year for democracy”

By Chauncey Devega 2 May 2022 (Salon) – Global democracy is sick. In the United States, Donald Trump’s supporters in the Republican Party continue to steamroll the Democrats and other pro-democracy forces. To say that the latter have for the most part been hapless, uncoordinated and paralyzed by denial is not overstating the case.  Political scientists and […]

Total greenhouse gas emissions from China and OECD nations, 1990-2019. In 2019, China’s GHG emissions passed the 14 gigaton threshold for the first time, reaching 14,093 million metric tons of CO2 equivalent (MMt CO2e). This represents a more than tripling of 1990 levels, and a 25 percent increase over the past decade. As a result, China’s share of the 2019 global emissions total of 52 gigatons rose to 27 percent.

Distribution of major tax cuts for the rich across OECD nations, 1965-2015. This figure visualizes the resulting binary variable that picks out years in which taxes on the rich were reduced substantially. In total, we identify 30 country-year observations where taxes on the rich were significantly reduced. Governments enacted major tax reforms in all countries in our sample and across the whole observation period. Many countries implemented major tax cuts for the rich in the late 1980s. Furthermore, the identification of tax cuts is also in line with previous studies that have focused on income tax progressivity (Rubolino and Waldenström, 2020) or on overall tax progressivity single specific countries (Saez and Zucman, 2019). For instance, echoing these authors’ findings, we find two major reforms that reduced taxes on the rich in the US: 1982 (First Reagan Tax Cut) and 1986/1987 (Second Reagan Tax Cut).

Tax breaks for the rich don’t boost the economy – “Our research shows that the economic case for keeping taxes on the rich low is weak”

16 December 2020 (LSE) – Major reforms reducing taxes on the rich lead to higher income inequality but do not have any significant effect on economic growth or unemployment, according to new research by LSE and King’s College London. Researchers say governments seeking to restore public finances following the COVID-19 crisis should therefore not be […]
