Direct comparison
Limitations vs. Delimitations Explained
How limitations differ from delimitations in a thesis or dissertation, with a comparison table, paired examples, and where each belongs.
Side-by-side comparison
| Dimension | Limitations | Delimitations |
|---|---|---|
| What it is | A weakness or constraint on the study caused by factors outside the researcher's control | A boundary the researcher deliberately set on the study's scope |
| Who controls it | Not the researcher — imposed by circumstance (funding, access, instrumentation, time, attrition) | The researcher — a conscious design decision |
| When it's decided | Identified during or after the study, often only fully apparent in hindsight | Set in advance, during study design, before data collection begins |
| Typical phrasing | “A limitation of this design is…” / “Due to X, the study was unable to…” | “This study was delimited to…” / “The sample was restricted to…” |
| Where it belongs in a thesis | Usually the Discussion or a dedicated Limitations section, near the end | Usually the Introduction or Methods, under a “Scope of the Study” heading |
| Effect if misclassified | Framing a real constraint as a deliberate choice reads as evasive | Framing a deliberate choice as a limitation makes it look like an unaddressed flaw |
| Typical examples | Small sample due to recruitment difficulty; a single self-report instrument; response bias; a short data-collection window forced by a funding deadline | Restricting the study to one country; studying only one population; a defined date range; adopting one theoretical framework over alternatives |
Common questions
FAQ
Are limitations and delimitations the same thing?+
No. Limitations are constraints outside the researcher's control, identified during or after the study. Delimitations are boundaries the researcher deliberately chooses in advance to define the study's scope.
Can the same study have both a limitation and a delimitation about the same feature?+
Yes. For example, restricting a survey to one country is a delimitation (a chosen boundary), while a low response rate within that country is a limitation (an unchosen constraint) — they describe different aspects of the same design.
Where do delimitations go in a dissertation?+
Conventionally in the Introduction, often under a “Scope of the Study” subsection, or at the start of the Methods chapter where population, sample, and variables are defined — stated before the reader encounters the detailed design.
Do all theses need a separate delimitations section?+
Not always — some programs require a combined “Limitations and Delimitations” section, others expect delimitations folded into the Methods chapter’s scope statement. Follow the specific program or journal’s formatting requirements, but keep the two conceptually distinct wherever they appear.
Is a small sample size a limitation or a delimitation?+
It depends on why the sample is small. If the researcher deliberately chose a small, focused sample (e.g., a multi-case qualitative design), that choice is a delimitation. If the sample ended up smaller than planned because of recruitment difficulty, funding, or time constraints, that is a limitation.
