Thanjavur, 
India
443,736 people lived in Thanjavur in 2025. It is the 1255th largest of the world's 12,138 cities, and the 199th largest in India.
That figure counts the whole built-up area, not the area Thanjavur governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Thanjavur grew
Where Thanjavur had 10 people in 1975, it had 35.9 in 2025.
On the UN's projection it will have 482,140 people in 2050. It passed 250,000 people between 1985 and 1990.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Where it is
How to read this: every dot is one of the 2,054 cities in India in 2025, and a dot's area is how many people live there, the biggest being New Delhi. The ringed dot in colour is Thanjavur; the grey dots are the rest. The outlines around them are neighbouring countries.
Area and built-up land · km²
How much land it covers
In 2025, Thanjavur covered 56 km², and buildings, roads and other built-up land covered 12 km² of it. That is 28 m² of built-up land for each person, about a square 5 by 5 metres. Since 1985, its built-up land has grown to 8.2 times its size, and its people have grown by 90%.
How to read this: the outer pale square stands for all the land the city covers, and the solid square inside it for the part with buildings, roads and the like on it. All three squares share a scale, so you can compare them by eye. A hatched one is a year the UN has projected.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Thanjavur are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Thanjavur publishes about itself: how the figures here are put together.
