The recent release of Fallout Shelter for Bethesda’s Android platform has been a huge success. As android users are new to this little tower rescue vault building sim with great details, they have more questions that come up than how to increase my vault dwellers. Here are some little tips to increase the population of your vault even if there are attacked or killed.
making babies:
The easiest way to increase the population in Fallout Shelter is to make babies. Right after the tutorial ends, about 12 wasteland dwellers show up at his vault door. But you need to match the pairs (one male dweller and one female dweller) and put them in the living room. After a while, you will notice that they will jump and run into the room, indicating that this pair will work. Later the male inhabitant leaves the room first and then the lady with a noticeably larger stomach. Now you can send this dweller back to work, as he will take 8 hours (in real time) A pregnant woman and children will not be involved in any incidents like fire and raid attacks.
Tip: If you double-tap the room, you can also see the conversation between the two of you.
Note: In larger quarters you can put multiple dwellers and they will pair up on their own.

Open the lunch boxes:
Making babies is indeed the easiest way, but it also has some drawbacks, such as you need to grow the child and you don’t have to start with very low SPECIAL stats. The second way to increase the number of inhabitants with good SPECIAL stats is Lunchboxes. When you open Lunchboxes you get 4 random cards and if you are lucky you might get a dweller with higher stats or characters from previous Fallout games (Special Character). As these dwellers are removed from random cards, you may occasionally not get a dweller. To win the Lunchboxes there are 3 ways:
- In-game purchase
- How to complete Hard Objectives
- Playing the game 7 days in a row (you receive a daily report score)

Construction of a radio station:
The radio station is unlocked when there are 20 or more inhabitants in the vault. The main goal of the radio station is to improve the happiness of the dweller inside the vault, and secondly, to reach the faraway wasteland, which increases the chance of a garbage man joining your vault. When the inhabitants start working on the radio station, the rooms count down and when it reaches zero a signal is broadcast in the wasteland in search of some residue that will appear on the door of your vault. Every time the countdown reaches zero, a single is sent to the wasteland inviting the dweller to his vault.
Hint: Place the inhabitants with the highest charisma in the radio station to improve the success rate.

Sending inhabitants to the wasteland:
This may or may not work, but when you send your dweller into the wasteland by dragging him out of the vault to explore. It seems that they invite some inhabitants when they meet during their exploration in the wasteland. And it happens that some dwellers appear at your vault door just after a few minutes you send your dweller. Try this exploration with the Higher Luck dweller.
