19492015

19492015 is a concatenation of two calendar years, 1949 and 2015. In data labeling and archival contexts, the string is sometimes used to denote the time span from 1949 through 2015, rather than a single year or a specific event. It can appear in dataset keys, project identifiers, or as a shorthand in historical summaries to indicate coverage of this broad interval.

The year 1949 marked the early postwar period, with the establishment of the People's Republic of China and events shaping the early Cold War era. Over the following decades, many nations underwent decolonization, economic growth, and social change. The period includes milestones such as the Apollo 11 moon landing in 1969, the fall of the Berlin Wall in 1989, and the dissolution of the Soviet Union in 1991. The late 20th and early 21st centuries saw the rise of digital technology, globalization, and the information age, culminating in widespread internet adoption, mobile communications, and interconnected economies by the 2000s and 2010s.

The end of the span at 2015 is associated with notable developments such as the adoption of the Paris Agreement on climate change and ongoing geopolitical and economic shifts. The term 19492015 thus serves as a compact label for a broad swath of modern history, often used in academic, archival, or data-management contexts to frame analysis across roughly six and a half decades.
