为什么我不能使用R package acs从SF1获得全国和ZCTA级别的评估？
为什么我不能使用R package acs从SF1获得全国和ZCTA级别的评估？
提问于 2017-03-05 05:40:53
以下是工作原理：
acs::acs.fetch(dataset = "acs",
endyear = 2015,
span = 5,
geography = acs::geo.make(zip = "*"),
variable = "B01001_001")也是这样做的：
acs::acs.fetch(dataset = "sf1",
endyear = 2010,
span = 0,
geography = acs::geo.make(state = "*"),
variable = "PCT0120001")请向我解释为什么下面的方法不起作用，因为这并不是因为人口普查API没有可用的邮政编码水平估计。我需要指定不同的地理位置才能从sf1和acs5中获得国家和ZCTA级别的估计吗？
acs::acs.fetch(dataset = "sf1",
endyear = 2010,
span = 0,
geography = acs::geo.make(zip = "*"),
variable = "PCT0120001")

您可以使用totalcensus package下载摘要文件并提取每个邮政编码中的数据。数据被下载到您自己的计算机上，因此访问数据不受人口普查API的限制。
library(totalcensus)
aaa <- read_decennial(
year = 2010,
states = "US",
table_contents = "PCT0120001",
geo_headers = "ZCTA5",
summary_level = "860"
)
print(aaa)

这似乎是2010年十年人口普查API的一个限制-数据不能通过API获得整个美国，而ZCTA数据只能按州获得。参见http://api.census.gov/data/2010/sf1/geography.html。
