Here's what you might be thinking of:
* Calendrical system: The Maya had a complex calendrical system that involved tracking the cycles of the Sun, Moon, and Venus. This wasn't about tracking people, but rather understanding the rhythms of nature and the cosmos.
* Record-keeping: The Maya kept meticulous records on a variety of topics, including historical events, births, deaths, and agricultural cycles. These records were often written on bark paper or stone monuments.
* Trade routes: The Maya were known to trade goods with other Mesoamerican civilizations. They likely kept track of trade routes and the movement of goods along them.
It's important to note that the Maya civilization was diverse and complex, and there were likely differences in how different Maya groups tracked information.
