How to express "tend to ~" in Chinese? According to a dictionary, tend to ~ is translated into the following words:

倾向
易於
走向
有～的倾向

But I think all of them are not used as often while reading, and thus is very awkward if I use them in writing. So there should be other expressions that mean tend to ~ in Chinese, for example in the following examples:

The developed countries tend to have less children.
Women tend to take jobs related to education, childcare, and health.

But in these cases, I think the words above are a bit awkward; I have never seen 易於 or 走向 are used while reading. So what words or expressions should I use to express tend to ~ in Chinese?
We actually often use 倾向于 but not 易于 or 走向.
