Pakdasht (Pers. پاکدشت , pronounced: Pākdasht) is a city in Iran, in the southeast of Tehran. The city is the administrative center of the central bakhsh shakhrestan Pakdasht.

History
On the site of Pakdasht in ancient times there were several rural settlements located in the Rey desert. Around 1300-1250. BC e. in the area of ​​modern Pakdasht, the culture of ceramics developed. In the 7th century n. e. the region was conquered by the Arabs. In the 8th c. there were several very large and important villages with more than 10 thousand people each. During the Qajar era, the land of the region was owned by members of the royal family. Under the Pahlavi dynasty, Reza Shah also captured several villages and handed them over to his heir. After the Islamic Revolution, in 1998, Shahrestan Pakdasht was officially established. Currently, many peoples live in the city, for example, Azerbaijanis, Kurds, Lurs, Persians, each people has its own customs, but there is a cultural unity between them. There are many attractions in the city and its environs, for example, the tomb of Imamzade Panjali, the tomb of Imamzade Auliya, the tomb of Imamzade “Chekhel-Dohtar” (literally: Forty daughters) and some other tombs, the ancient ice cellar Bir-Daglan, a bridge over the local river, built under the Qajars and registered as a national heritage of Iran.

Demographic dynamics
The city’s population, according to the last three official censuses (October 1996, October 2006 and October 2011), was 49,220, 126,937 and 206,490 respectively, thus quadrupling over the entire period. This is a very high pace. The population of the city grew very rapidly in 1996-2006: approximately 99 ‰ on average per year. Such colossal growth rates cannot be achieved even with the highest possible birth rate, which, however, apparently was observed at that time in Pakdasht. But its maximum level is only about 50-55 ‰ per year, or two times less than the recorded figures for urban population growth. Therefore, it is obvious that the main part of the recorded population growth was given by mass migrations. In 2006-2011 the average annual overall growth rate of urban residents increased, even more exceeding the maximum possible birth rates: they amounted to 102 ‰. Schedule The growth of the city’s population has a pronounced hyperbolic form, which means that the relative, as well as absolute, growth rates of its population are growing year by year. In general, for 1996-2006. on average, the city’s population grew by 7,800 people per year, and in 2006-2011. — by 15,900 people, or 2 times more. The share of the city in the total population of Tehran province also increased sharply: in just 5 years it rose from 1.1% in 2006 to 1.7% in 2011. If we take the population of Tehran itself (without suburbs) as 100%, then in In 1996, only 0.7% of this number lived in Pakdasht, but in 2006 – already 1.6% (+0.9%), and in 2011 – 2.5% (also +0.9 %).

Thus, the growth of the population of Pakdasht significantly outstrips its growth in the capital of the country, probably both due to the much higher birth rate of the local population and due to mass migration. Особенностью населения Пакдашта является резкое преобладание мужчин: их по переписи 2011 г. было 105,8 тыс. человек, а женщин — только 100,7 тыс. Иными словами, в городе на 100 женщин зарегистрировано более 105 мужчиn. This is due to the pronounced youth of the local population, that is, a high percentage of children and young people, among whom, as a rule, males predominate sharply, and a low percentage of the elderly, among whom women usually predominate. Due to the youth of the population, a very high growth rate in the number of urban dwellers will continue to be observed, although it is likely that in the coming years there will still be a retreat from excessive growth rates, since double-digit average annual growth is extremely high and cannot continue indefinitely. They will have to gradually begin to decline, primarily due to a decrease in the rate of migration, which will happen when a sufficiently large number of people have already moved to the city, which means that the migration reserves will significantly decrease: there will be no one to migrate because everyone who wanted to move to Pakdashthave already moved into it. When the city reaches a sufficiently high population (approximately 500 thousand people), its birth rate will also have to fall sharply, since in the conditions of modern Iran, the birth rate in large cities falls quite quickly. This will cut off the second source of the rapid growth of the urban population. When all these processes happen, we can expect a rapid drop in the current population growth rate of Pakdasht: in 2, 3 and even 4 times – to the average level characteristic of large cities in the developing countries of the Middle East.
