Using a sample of 23 developed countries, this paper looks at rail line maintenance cost per capita in the year 2020 versus rail line maintenance cost per capita in the year 2100. This analysis can be applied to most other infrastructure maintenance costs in the future.Design/methodology/approach However, this paper focuses on one vital consequence which is that future infrastructure maintenance cost per capita will increase. Using a sample of 23 developed countries, this paper looks at rail line maintenance cost per capita in the year 2020 versus rail line maintenance cost per capita in the year 2100. This analysis can be applied to most other infrastructure maintenance costs in the future.Findings The findings show that trail line maintenance costs per capita in the year 2100 will increase significantly for most developed countries.Research limitations/implications This research shows the negative consequences of declining birth rates in a very vital and important area.Practical implications Despite declining birth rates and population decline in the future, many infrastructure systems still need to be maintained.Social implications Maintaining the infrastructure will extract increasing amounts of vital national resources away from other societal concerns.Originality/value From an extensive literature review, very little, if any, has been written on this subject. Yet, this topic is highly important and will continue to get more focus in the future. 收起
