Ohm. Because of that surface resistivity and the surface resistance are often mixed up. In order to differentiate between the two, surface resistiv-ity is often expressed also in Ohm/square (Î©/sq.) which is not a valid unit from the dimensional anal-ysis point of view. 2 Surface resistivity and surface resistance 2.1 Current density and surface cur-
The median age of the world's population was estimated to be 30.1 years in 2016, with the male median age estimated to be 29.4 years and female, 30.9 years.
In 2011, the percentage of the population aged 65 and over in New Brunswick was 16.5%, compared with a national percentage of 14.8%. The percentage of the working age population (15 to 64) was 68.4% and the percentage of children aged 0 to 14 was 15.1%.
