By 1996 foreign-born immigrants who arrived before 1970 had a home ownership rate for 75.6 percent, higher than the 69.8 percent rate among native-born Americans.
表述一定要准确！不是 higher than 后的成分作什么成分，而是包含 higher than 在内的整个黑体部分做什么成分。作 75.6 percent 非限制性定语，进一步说明这个数字如何。也就是说，相当于：which was higher than the 69.8 percent rate among native-born Americans，先行词是75.6 percent。
