要找 Census 變數 ID，可用：

線上資源，如 Census Reporter
tidycensus 內建的變數搜尋

選擇要搜尋的資料集

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

篩選變數資料集

library(tidyverse)
B19001 <- filter(v16, str_detect(name, "B19001"))
B19001

ACS 變數結構

ACS 變數 B19001_002E 結構：

B：代表 base 表。其他前綴：C、DP、S。
19001：表格 ID
002：表內變數代碼
E：代表 estimate。
- 在 tidycensus 函式中屬於可選，函式會對每個變數同時回傳 E 與 M。

一起來練習吧！
