drush sqlq 'select count(node.nid) as node_count, node_type.type from node inner join node_type on node.type = node_type.type group by node_type.type'

And then if you want filter by a specific type, just use grep like this:

drush sqlq 'select count(node.nid) as node_count, node_type.type from node inner join node_type on node.type = node_type.type group by node_type.type' | grep 2014
