It can be tricky to find studies that analyze state- or national-level data rather than individual beliefs. Here are some things you can try:
- Search the phrase "national study" or "state study" in Abstract (AB). See Image 1 below.
- Search for a specific state or nation as LOC (Location). See Image 2 below.
- Search for a phrase that includes the place name, like "United States study," in the ABSTRACT (AB).
