QCEW Open Data Access: Sample Code and Examples
QCEW provides a collection of CSV files representing logical slices of data. Data are sliced by industry, by area, and by establishment size-class. The QCEW data slices can be directly accessed from various programming languages. QCEW has made an effort to provide simple examples in several different languages. These examples are provided as is and may be outdated. Some modification may be necessary to successfully retrieve data. These examples are intended to be stepping stones for advanced data users and software developers: They are not necessarily the optimal solution of their respective environments.

- Getting Data with SAS
- Getting Data with R
- Getting Data with Perl
- Getting Data with Python
- Getting Data with C#
- Getting Data with Java
In June 2016, these examples were updated to access the new storage location. The CSV files are now stored
on data.bls.gov instead of www.bls.gov. The rest of the URL structure remains the same. These example were
also updated to handle for certian case-sensitivity issues with the area fips and quarter identifiers. A
server-side redirect points the older versions to the new location. This redirect will be turned off
at some point in the future. We recommend you update your codebase with the new versions above.

The QCEW open data files can be directly imported into an Excel Spreadsheet using VBA.
An example of this VBA code can be downloaded from the link below. The example workbook
is saved in the ".xlsb" format. You'll need to enable VBA Macros for this example to function
properly. For convenience, we have also provided a legacy version compatible with the Excel 97-2003 format.

The QCEW open data files can be imported into SAS using the SAS macros defined in
this example. Each macro imports data as a SAS data set. This example can be downloaded
from the link below. The version below was tested with SAS 9.3 and may require modification
for different versions.
The QCEW open data files can be imported using the R programming language.
This example provides three functions that will import QCEW CSV files
that are stored on the BLS Web Site. Data are converted from CSV files to data frames.
A link to this example is provided below. This R Script was tested on R
version 3.1.0 and may require modifications for different versions.
R Example (RScript - R Language 3.1.0)
The QCEW open data files can be accessed from within Perl using a simple get request.
This example provides three subroutines that get CSV data from the BLS Web Site.
Each subroutine builds and returns a 2-dimensional array representing the rows and columns
of data in underlying CSV files. The header row is included as row zero. This
code targets Perl 5.20.0 and may require modifications for different versions.
Perl Example (Perl 5.20.0)
The QCEW open data files can be accessed from within Python using the "urlopen" command.
There are two links below. The first link provides an example
for Python 2.x and the second link provides an example for Python 3.x. Both versions
provide the same 3 functions. These functions get CSV data from the BLS Web Site and
convert it into a 2-dimensional array representing the rows and columns of the CSV
file. Headers are included in row zero. These two versions were tested specifically
with Python 2.7 and Python 3.3 and may require modification for other versions.
Python 2.x Example
Python 3.x Example
The QCEW open data files can be accessed from PHP. They can also be accessed from the
The first example provides three simple PHP functions that return data by area, industry,
and establishment-size class. Data are returned in 2-dimensional arrays representing the
rows and columns of the csv file.
The QCEW open data files can be accessed from C#. There are two different links below.
The first link provides just the Qcew.cs file. This file defines a static class that exposes
three static methods. These methods get CSV data from the BLS Web Site and return populated
The second link provides a zipped console project. This project includes the QCEW.cs and a
few example calls within the Program.cs file. This project was created in Microsoft Visual
Studio 2010 and targets the .NET 2.0 Framework. This example should work with later versions
of the .NET Framework. However, some modification may be necessary.
Qcew.cs (Library Only)
C# Example Project
The QCEW open data files can be accessed using Java. This example provides a single class
with three static methods. These methods get CSV data from the BLS Web Site and
convert it into an ArrayList of String Arrays where each ArrayList item represents a row
and the elements of the String Array represent the values in each column of the CSV
file. Headers are included in ArrayList item zero. This example was tested with Java 1.7
and may require modification for other versions.
