Population Census Chronology and Growth Trends
Tracking population changes over time is essential for understanding the growth and development of a region. A census—the official process of systematically counting and recording a population—provides a statistical snapshot that reveals how a society expands and evolves across decades.
By analyzing historical census data, we can identify periods of rapid acceleration and steady growth, offering insights into the demographic shifts that shape infrastructure and resource planning.
Key Facts
- The first recorded census in this series took place in 1836 with a population of 1,873,736.
- The population grew from approximately 1.87 million in 1836 to over 31.2 million by 2017.
- The largest single increase between two census periods occurred between 1876 and 1940, with an addition of 4,324,006 people.
- The most recent recorded census in 2017 shows a total population of 31,237,385.
Detailed Population Analysis
The demographic trajectory began with modest growth in the mid-19th century. Between 1836 and 1876, the population grew steadily, crossing the 2 million mark by 1850 and reaching nearly 2.7 million by 1876.
A significant shift occurred in the 20th century. By 1940, the population surged to over 7 million, marking a massive increase of more than 4.3 million people compared to the previous count. This upward trend continued aggressively through the latter half of the century, with the population exceeding 10 million by 1961 and 22 million by 1993.
Modern Growth Patterns
In the 21st century, the growth rate remained strong. Between 2005 and 2017, the population climbed from 26,152,265 to 31,237,385. This indicates a consistent expansion of the population base over the last several decades.
