Wen Ji now works in the household department - the head of the household department is thin, and he is a lieutenant colonel-level official in Huaxia (Huaxia has not yet completely separated the soldiers and the people, and more than 90% of the fair people still have military positions).

His main task was to compile the data reported by the provinces of the empire - including population, industrial and agricultural production (economically, the empire now does not count GDP, but statistics such as the gross value of industrial and agricultural production).

These statistics are very important and have great significance for the Empire to formulate the budget for the new year and the completion of the five-year plan.

And one of the most important numbers is population.

At present, the population of China, including the common people and slaves, is about 15 million, and the annual population growth rate of the public and common people is more than 1.5 percent.

A large part of this figure comes from the return of displaced people from Jiangnan to Jiangbei, as well as some Jiangnan people to settle in Jiangbei, in addition to a small number of ordinary people who have been promoted to commoners.

Excluding this part, the growth rate of the population that depends on fertility (minus the number of deaths) is about 1.2 to 3 percent.

According to Wen Ji's summary statistics, there is a process of transformation in the population growth point of the public and commoners, and the number of immigrants who used to have access to a large number of people every year is declining, because the Han people in Jiangbei have all been included in the imperial rule, and the immigrants in Jiangnan have also decreased with the decrease in the number of displaced people.

But the fertility rate of the population in the empire was rising, and the mortality rate was falling rapidly.

One reason for this is that the society within the empire has stabilized, foreign enemies can no longer pose a threat to the empire, and the population lost in war is getting lower and lower than before.

Another reason is the rapid development of imperial medicine.

Shortly after the occupation of Taiwan, the medical department of the Imperial Academy of Sciences invented cowpox to prevent smallpox, which led to a sharp decline in the number of smallpox deaths in the empire.

The Cabinet had a plan to eradicate smallpox by inoculating all the people of the empire, including commoners and slaves, within five years.

In addition, the penetration rate of sulfonamides is increasing, and the price of this thing is still very expensive, and the common people and slaves still can't afford it, but when the public and civilians are in need, they can reimburse part of the expenses through medical insurance, which also effectively reduces the mortality rate of the population.

The Bureau of Statistics, to which Wen Ji belongs, estimates that in five years, when the pox is fully spread and the production of sulfonamides increases, the population growth rate of the imperial public and commoners will reach about 2 percent, even if the foreign population is not counted.

This figure is satisfactory enough, after all, the empire can still count on eliminating the Great Zhou regime in Jiangnan within five years, and bringing the population of Jiangnan to 50 or 60 million under its jurisdiction.

As for the slave and common population, the rate of growth has been very low.

There are many reasons for this:

First, the mortality rate of commoners and slaves was very high.

Their nutritional supplements are far inferior to those of the public and civilians, and the work they do is usually much heavier, and the medical security cannot keep up, so the natural mortality rate is high.

Second, there is the opportunity for commoners to be upgraded to civilians, which will also lead to a depopulation in this area.

In fact, the easiest way to upgrade is not the military exploits advertised by the empire, but the fact that a woman marries a Han Chinese and usually has the opportunity to upgrade after giving birth to an heir.

After all, young women make up a large proportion of the common people and slaves, so many people are freed from slavery every year.

Third, the chances of commoners and slaves being able to marry wives are very small, so the fertility rate has been low, which is also an important factor affecting population growth.

Therefore, the population of common people and slaves will have zero or even negative growth in the simple fertility rate minus the mortality rate.

The reason why the population of these two classes increased greatly every year was because as the area conquered by the empire expanded, many alien races were turned into slaves in whole groups.

Basically, every time the empire conquered a new territory, there was a straight line of elevation of the commoner and slave populations on the chart, and this was when the people in the bureau were at their busiest - they had to complete the statistics of population growth before the new annual meeting season.

"Before the war, we estimated that there were three million people in Pseudo-Xia."

Wen Ji said to his wife:

"There will be a large part of the losses in the war, it is estimated that there will be 80 to 1 million people, and the rest will have some outcasts of Han Chinese to distinguish, but it is estimated that 100 to 1.2 million slaves will still be added."

"This is only the population of the pseudo-Xia, and now there is a Fusang battlefield on the Eastern Sea, and it is expected that there will be more slave population available there."

"So the war is won, and my work is going to be busy."

"It's really hard." Xu Shimei smiled: "It sounds very tired." ”

"yes, not like you." Wen Ji joked: "Three months of paid leave during pregnancy, I think when I work overtime, it would be nice if we men could have children." ”

"Heh, man......, Ye Gong is a good dragon."

……

In May 1793, the Chinese Empire officially announced the recovery of the territory that had been stolen by the Pseudo-Xia for decades.

The sphere of influence of the former pseudo-Xia, part of the eastern part was divided into Shaanxi Province; Its core Hung Linh region and part of the interior were merged to form the new Ning Province; To the west of Liangzhou, including Ganzhou, Suzhou, Guazhou, and Shazhou, all the way to the area around Yumen Pass, it was divided into the new Gan Province.

As for the northern region of the former Pseudo-Xia, there are large areas of desert, including the Black Mountain Weifu Military Division and the Heishui Town Yan Military Division in Hetao, which were merged into Montenegro Province.

In this way, the empire gained three new provinces with a population of at least 2.1 million, basically eliminating the military threat to the northwest, while also forming a semi-encirclement of the Mughal steppe.

……

On the other hand, as the final end of this Pingxia War, after Zuo Helin's troops left Yumen Pass in the west, they annihilated the allied forces of the Western Regions in Gaochang and Loulan and occupied Gaochang in May; Occupy Qiuzi in June; Occupy Usun in July.

After the news of the demise of the Pseudo-Xia reached the Western Regions, the rest of the Western Regions countries surrendered to Zuo Helin one after another - they didn't want to be caught between the two giants of Huaxia and Pars, so they could only choose sides.

At the beginning of August, the Zuo Helin battle group arrived at the Green Ridge and confronted the Pars people across the Green Ridge.

The two sides did not fight directly, because the commander of the Pars side was Dalke, who had traveled in Qi Province, and both sides felt that the other did not seem to be easy to mess with, so they both kept their calm.

Although everyone knows that this is only a temporary calm.

Zuo Helin and Darker reached a series of temporary peace agreements, in which both sides agreed not to cross the ridge (because whoever crossed the ridge to attack would be dragged down by the ridge), but allowed merchants and no more than a hundred guards to trade between the two armies and the two countries.

Taking advantage of the short period of stability in the Western Regions, the Chinese side planned the various ethnic groups in the Western Regions into eight foreign countries: Gaochang, Qiuzi, Wusun, Khotan, Jingjue, Loulan, Shule, and Yanqi.

Like other foreign countries, these countries received comprehensive "guidance" from China in terms of military, diplomatic, and educational.
