were characterized by their approaches to sampling and interviewing, I expect that the third era of survey research will also be characterized by the linkage of surveys with big data sources(Table 3.1).
These sources of change are sometimes interesting research questions, but these changes complicate the ability of big data sources to track long-term changes over time.
These four examples all show that a powerful strategy in the future will be to enrich big data sources, which are not created for research, with additional information that makes them more suitable for research(Groves 2011).
linking surveys and big data sources(section 3.6).
Thus, when big data sources appear to reproduce predictions of social theory,
But, as was described in chapter 2, big data sources may not be accurate, they may not be collected on a sample of interest, and they may not be accessible to researchers.
First, I will argue that big data sources will not replace surveys and that the abundance of big data sources increases- not decreases- the value of surveys(section 3.2).
Thus, when big data sources appear to reproduce predictions of social theory, we must be
Given that more and more of our behavior is captured in big data sources, such as government and business administrative data, some people might think that asking questions is a thing of the past.

First, I will argue that big data sources will not replace surveys and that the abundance of big data sources increases-not decreases-the value of surveys(section 3.2).
First, in section 2.2, I describe big data sources in more detail and clarify a fundamental difference between them and the data that have typically been used for social research in the past.
The practical and fundamental limitations of big data sources, and how they can be overcome with surveys, are illustrated by Moira Burke and Robert Kraut's(2014) research on how the strength of friendships was impacted by interaction on Facebook.

Many social scientists are already familiar with the process of cleaning large-scale social survey data, but cleaning big data sources is more difficult for two reasons:
In enriched asking(section 3.6.1), the big data source has a core measure of interest and the survey data builds the necessary context around it.
Table 2.8: Studies That Use a Big Data Source to Predict Some Event.
In amplified asking(section 3.6.2), the big data source does not have a core measure of interest, but it is used to amplify the survey data. .
In enriched asking, a big data source contains some important measurements but lacks other measurements so the researcher collects these missing measurements in a survey and then links the two data sources together.
The ingredients are(1) a big data source that is wide but thin(i.e., it has many people but not the information that you need about each person)
