The village's population has mostly stayed between 130 and 200 since the 13th century. In 1565 the village was 13 oxgangs in size. The village was practically uninhabited after the Polish-Swedish war in 1615, while the nearby villages of "Jaunack" and "Karrock" remained practically untouched. The village recovered from the demographic crisis by the second half of the 17th century. By 1660s, Kehra manor owned all the nearby lands, including Kehra village. The manor's lands were ravaged by the bubonic plague in 1710 and 1711, only 14 out of the previous 146 inhabitants survived. The population recovered to pre-plague levels in approximately 40 years. By 1856, Kehra village had transformed from a clustered settlement to a linear settlement.
