I want to know the answer to the following question:
How dense was the population of Kathmandu in 1991?
All the background I'm provided with is that "With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.". Is that enough to answer the question?
Answer: yes
