The European Social Survey (ESS) is an academically driven cross-national survey that has been conducted across Europe since its establishment in 2001. Every two years, face-to-face interviews are conducted with newly selected, cross-sectional samples. The survey measures the attitudes, beliefs and behavior patterns of diverse populations in more than thirty nations. Taken from the ESS website.
Note: The essurvey package was originally called
ess. Since essurvey 1.0.0 all
ess_* functions have been deprecated in favor of the
import_* and download_* functions. Also,
versions less than and including essurvey 1.0.1 returned
wrong countries. Please install the latest CRAN/Github version.
The essurvey package is designed to download the ESS
data as easily as possible. It has a few helper functions to download
rounds (a term synonym to waves to denote the same survey in different
time points), rounds for a selected country and to show which
rounds/countries are available. Check out the vignette and other
documentation in the package’s website for
more detailed examples of the essurvey package.
You can install and load the development version with these commands:
# install.packages("devtools") in case you don't have it
devtools::install_github("ropensci/essurvey")or the stable version with:
install.packages("essurvey")First, you need to register at the ESS website, in case you haven’t. Please visit the register section from the ESS website. If your email is not registered at their website, an error will be raised prompting you to go register.
Set your valid email as en environment variable.
set_email("your@email.com")To explore which rounds/countries are present in the ESS use the
show_*() family of functions.
library(essurvey)
show_countries()
#> [1] "Albania" "Austria" "Belgium"
#> [4] "Bulgaria" "Croatia" "Cyprus"
#> [7] "Czechia" "Denmark" "Estonia"
#> [10] "Finland" "France" "Germany"
#> [13] "Greece" "Hungary" "Iceland"
#> [16] "Ireland" "Israel" "Italy"
#> [19] "Kosovo" "Latvia" "Lithuania"
#> [22] "Luxembourg" "Montenegro" "Netherlands"
#> [25] "Norway" "Poland" "Portugal"
#> [28] "Romania" "Russian Federation" "Serbia"
#> [31] "Slovakia" "Slovenia" "Spain"
#> [34] "Sweden" "Switzerland" "Turkey"
#> [37] "Ukraine" "United Kingdom"To download the first round to use in R:
one_round <- import_rounds(1)This will return a data frame containing the first round. Typically,
the European Social Survey data files comes with a script that recodes
missing values to NA for different programs (Stata, SPSS,
SAS).
Use recode_missings to recode all values
automatically.
library(tidyverse)
one_round <-
import_rounds(1) %>%
recode_missings()See the package vignette for greater detail or see the help page with
?recode_missings. You can also download several rounds by
supplying the number of rounds.
five_rounds <- import_rounds(1:5)This will download all latest versions of rounds 1 through 5 and return a list of length 5 with each round as a data frame inside the list.
You can check the available rounds with show_rounds()
because if you supply a non existent round, the function will return an
error.
two_rounds <- import_rounds(c(1, 22))
#> Error in round_url(rounds) :
#> ESS round 22 is not a available. Check show_rounds() Alternatively, you can download all available rounds with
import_all_rounds().
You can also download rounds by country:
dk_two <- import_country("Denmark", 1:2)Use show_countries() to see available countries and
show_country_rounds("Denmark") to see available rounds for
chosen country. Alternatively, use import_all_cntrounds()
to download all available rounds of a country.
You should be be aware that data from the ESS survey should by analyzed by taking into consideration the sampling and weights of the survey. A useful example comes from the work of Anthony Damico and Daniel Oberski here.
I’m quite aware that most ESS users don’t know R, that is why the
package also allows to download the data in Stata, SPSS or SAS format
with just one line of code. Instead of the import_*
functions, use the download_* functions.
download_rounds(c(1, 2),
output_dir = "my/new/directory",
format = 'spss')This will save the ESS rounds into separate folders and unzip them in
the specified directory (if you want to know your current directory,
type getwd()). This works the same way for
download_country(). Be aware that if you download the files
manually you should read them into R with the haven package
for all essurvey related functions to work.
