How many people worldwide have no access to electricity?

How to get close to this number

Work from the share. The explanation gives it as roughly one in twelve people worldwide, and world population is around eight billion. A twelfth of eight billion is a few hundred million — and reasoning from a share rather than an absolute number is almost always easier when the quantity is global.

The concentration is the part that should shape how the figure is read: over eighty percent of those without power are in one region. A global statistic here is really a regional one, and interventions that treat it as evenly distributed will misallocate almost everything. Aggregate figures hide geography, and this one hides it almost completely.

The trend is the genuinely important detail. The number fell steadily for two decades and then stalled, which means the remaining population is the hardest to reach — rural, dispersed, and expensive to connect to a grid. Progress on any metric slows as it approaches the tail, and a stalled figure usually signals that the easy gains are exhausted rather than that effort stopped.
