# Should there be paragraph break between a leading text and itemized list?

What is the right convention for rendering itemized-lists?

Is it like this without any paragraph break between the previous line and the list?

\documentclass{article}
\begin{document}
There are 10 types of people in this world:
\begin{itemize}
\item Those who understand binary.
\item Those who don't.
\end{itemize}
\end{document}


Or is it like this with a paragraph break between them?

\documentclass{article}
\begin{document}
There are 10 types of people in this world:

\begin{itemize}
\item Those who understand binary.
\item Those who don't.
\end{itemize}
\end{document}

• Would you consider the entries to be part of the former sentence? If yes, did you ever make a paragraph break within a sentence? Apr 8 '18 at 10:02

LaTeX explicitly tests for this case. If there is a paragraph break before the list the vertical space is adjusted (\partopsep rather than \topsep) and the text following the list starts a new paragraph.
• in the example given it is part of the preceding sentence (: doesn't end the sentence) so there should be no paragraph break) Apr 8 '18 at 10:55
• slippery keyboard (s/\partopdep/\partopsep)
