Estimates show that around 19 million birds of house crow lives in urban areas while on the other hand around 15 million birds of the house crow lives in rural areas. 
IUCN Status
Due to extremely wide range, this species does not approach threshold for Vulnerable under criterion of range size (range of occurrence <20000 km2 including population size, fluctuating or declining range, habitat extent and small number of location and fragmentation). Its population appears to be stable and species don’t approach the threshold of Vulnerable under criterion of population trend (> 30 % fall over ten year or three generation). 
Population size has not been yet quantified against the threshold for Vulnerable under criterion of population size (< 10000 mature and interbreeding individuals with continuous decline of 10 % in 10 years). Keeping in view, these reasons the species has been categorized as Least Concern. 
House crow builds nest from sticks in hidden places on a large tress which has wide crown but rarely on power poles and construction structures. They give mostly 3 to 6 eggs in a nest and make another nest to lay more eggs but on the same tree. Their eggs are pale blue-green speckled with the brown color. In Asian countries, their nest are sometime occupied by other bird such as Asia Koel. The Corvus splendens found in numerous number but their population is slightly decreased. They are such species which falls in the category of low conservation. Their population was decreased either due to some disease and their loss in some areas are severe.
