    Data Analytics, Health Outcomes Externship with ARCeH

    Here’s what the data says: put a pin in Bangkok. Draw a five-hour flight radius around it. You just circled half the world's population. And half of those people are kids under five, an age where survival itself isn't guaranteed. Five isn't an arbitrary number: it's the line researchers use as a proxy for a country's overall health, because almost every preventable childhood death, driven by a bad water source, poor air quality, or an infection nobody caught in time, happens before it. Clear five, and the odds of reaching adulthood jump astronomically. Don't, and the cause almost always traces back to poverty, healthcare access, environmental risk, or nutrition, something that could have been mapped, measured, and prevented in time. That's the gap this externship exists to close: turning scattered, messy public data into a specific, defensible answer about what's actually driving that risk in a given place, and pass it to the people at ARCeH who want to know about it.

Overview

The externship converted public health and environmental datasets into analytic findings about factors linked to under-five mortality within a multi-country region centered on Bangkok. The work defined analytic scope, prepared data for correlational analysis, and compared indicators such as water quality, air pollution, nutrition, and healthcare access. Outputs included cleaned datasets and a set

What I've accomplished

I identified a daily child-casualty dataset, evaluated its structure and variables with a dataset fitness checklist, and confirmed it met criteria for structure, unit, variables, sample size, missingness, and pairing.
