Day 30 #30DayChartChallenge — Global Health Data Exchange Day Since 1990, global life expectancy has increased by 6 years. Beating enteric and lower respiratory infections contributed the most, while COVID-19 subtracted 1.6 years. Net gain: +6.0 years. Data: IHME GBD 2021 Tools: R + ggplot2

Horizontal waterfall chart on a dark navy background titled "How the world gained six years of life". Each row is a leading cause of death; each bar shows that cause's contribution to global life expectancy from 1990 to 2021, stacking cumulatively. Eight teal gain bars step right: enteric infections +1.12 years, lower respiratory infections +0.90, stroke +0.72, other communicable diseases +0.62, cancer +0.57, ischaemic heart disease +0.56, neonatal disorders +0.55, tuberculosis +0.52. A lavender bar rolls up ten smaller gains at +2.57 years. Two loss bars step back left: other pandemic-related mortality −0.52 (red) and COVID-19 −1.60 (orange). A final orange bar at the bottom shows the net change, +6.01 years, beside a large "+6.0 years of global life expectancy" callout. Source: IHME Global Burden of Disease Study 2021.

Day 28 #30DayChartChallenge — Modeling Five futures, one planet Three demographic models project vastly different 2100s: UN (peak 10.3B in 2083), IHME (peak 9.7B in 2065, then decline), and Wittgenstein SSPs (9.2B to 13.1B). Data: UN WPP 2024 · IHME GBD 2020 · Wittgenstein SSPs Made with R + ggplot2

Line chart on a dark navy background titled "Five futures, one planet." World population from 1950 to 2100 in billions. A single white line shows observed history rising from 2.5 B in 1950 to 8.1 B in 2023. From 2023 the line splits into five projection paths: a coral UN WPP 2024 line peaking at 10.3 B around 2083 and ending at 10.2 B in 2100, surrounded by an 80 % and 95 % prediction-interval ribbon that fans outward; a blue IHME GBD 2020 line peaking earlier at 9.7 B in 2065 and falling to 8.8 B in 2100, with its own pale-blue 95 % uncertainty ribbon; three Wittgenstein SSP scenarios — green SSP1 declining to 8.0 B, yellow-green SSP2 ending at 9.9 B, and amber SSP3 still rising to 13.1 B at 2100. Each line is labelled at its 2100 endpoint with the model name and final value. The UN's 95 % prediction interval visibly brackets most of the disagreement between models.
