搜索普查变量

要查找普查变量 ID，可使用：

在线资源，如 Census Reporter
tidycensus 内置变量搜索

选择要搜索的数据集

v16 <- load_variables(year = 2016,
                      dataset = "acs5",
                      cache = TRUE)                    
v16

ACS 变量结构

ACS 变量 B19001_002E 结构：

B：表示基表。其他前缀：C、DP、S。
19001：表 ID
002：表内变量代码
E：表示估计值。
- 在 tidycensus 函数中可选，这些函数会为每个变量返回 E 和 M。
