Why do missionaries have large families?

Missionaries often have large families for several reasons, including cultural and religious beliefs that emphasize the value of children and family life. In many religious communities, large families are seen as a blessing and a way to fulfill the commandment to "be fruitful and multiply." Additionally, having more children can help ensure that the family's mission work continues through future generations. Practical considerations, such as the need for helpers in their ministry, can also play a role in their decision to have larger families.
