About these units
Century (century)
A century equals 100 years and is a major unit of historical, demographic, and civilizational analysis. Historians frequently divide narratives into centuries to highlight long-term transformations—technological revolutions, empire rises and falls, or artistic movements. Sociologists study century-scale changes in population, urbanization, and cultural evolution. Although human lifespans rarely exceed one century, this unit is large enough to encompass sweeping societal changes, making it ideal for macrohistorical studies.
Decade (decade)
A decade spans 10 years and is widely used in demography, sociology, climatology, economics, and culture. Statistical studies often examine decade-level patterns—population change, economic cycles, consumer trends, cultural shifts, and generational studies. Climate scientists assess long-term temperature and precipitation changes over decades to filter out short-term variability. Decades also anchor cultural memory: the "60s," "80s," or "2000s" evoke distinct historical moods, fashions, and political climates. A decade, though arbitrary in length, has become a meaningful cultural and scientific periodization tool.
