This study overviews the keywords overspending, family, and sustainable budget from different perspectives in the existing literature. Its goal is to identify the gap through keyword analysis and formulate a methodological direction for the future, using an overview of the methodologies used for researching individual keywords. This publication is based on a systematic literature review, including articles from the Web of Science, Science Direct, and Scopus databases. The resulting publications are analyzed from several angles, such as the number of publications per keyword per year, which methodologies were applied, and at which level (micro, meso, macro) the topic was previously researched. As an output of the partial analyses, both the lack of research on the sustainable spending habits of Hungarian households and the need for a methodology that can be applied for this purpose emerges. The results enable the development of a combined method, with which current research can be carried out on a micro level regarding sustainable spending habits in Hungary.

Based on the available statistical data, most employees travel by car, which results in traffic jams, hurts the environment, and increases household expenditures. As a result of this phenomenon, our investigation aimed to present the global trends in urban mobility. It is also considered preliminary research of Hungarian transportation habits and trends by summarizing the standard fees of taxi service, parking, and maintaining a driving license. As our research methodology, we chose a systematic literature search and a summary of the available secondary data to present the main global trends characterizing urban mobility and the standards typical of Hungarian transport. The results enable the expansion of the research and provide an opportunity to learn about consumers’ attitudes at the national level.
